33 Different Types of Goldfish Breeds

If you want to know how to identify what type of goldfish you have, you need to look at its features. Here are some unique features that make identifying your goldfish simple. There are hundreds of types of goldfish, many that have been cross bred which take on a mix of different features.

Hardy Goldfish Types

A body shape that has an elongated flattened football shape include: The Common, the Comet, Shubunkin. (good breeds for an outdoor goldfish pond).The common, comet and shubunkin look very similar in shape and colors.

  • The comet has longer fins and most notably its tail fin is much longer.
  • The common doesn’t come in calico but the comet and shubunkin do.
  • The shubunkin is only calico so if it’s calico with short fins, it can’t be a common.

Fancy Goldfish Types

An egg shape body shape are considered the fancy breeds and can include: Fantail, Ryukin, Veiltail, Oranda, Telescope, Black Moor, Panda Butterfly, Ranchu, lionhead, Pompon, Pearlscale, Hama Nishki, Celestial and Bubble-Eye.The mature oranda, ranchu and lionhead has a wart like wen hood cover over its face and head

  • The oranda has a dorsal fin and the lionhead and most ranchu don’t.
  • The ranchu has a prominent arch in its back and downward pointed tail fins.
  • The lionhead and oranda have a straighter back line.
  • A goldfish with a hood cover with a straight back and no dorsal fin is a lionhead.

The fantail, ryukin and veiltail have similar egg-shaped bodies with no distinct features like a hood cover or globe eyes

  • The fantail and ryukin have sturdy upright fins and tails.
  • The ryukin has a more prominent hump that the dorsal fin sits on than the fantail.
  • The veiltail has long flowing fins and tail.

The telescope, black moor and panda butterfly have their eyes on the sides of ball like protuberances

  • A black moor is a telescope/globe-eye but is only black or faded black in color.
  • The panda butterfly resembles the colors of a panda bear, clear sections of black and white.

The pearlscale and hama nishiki have a golf ball body shape with scales that stand out like little white domes

  • the hama nishiki has a slight hood cover on top of its head while the pearlscale does not.

The celestial has bulging eyes that point upward and no dorsal fin.The bubble eye has two bubble shaped check pouches

The Common Goldfish

Carassius AuratusAsian in origin, the common goldfish is a member of the Cyprindae fish family. The common goldfish is related to the many species of carp, koi and other types of breeds. The name Auratus literally means “overlaid with gold”. This species of fish has been raised by humans for over a thousand years and sometime during this period, they became family pets.common goldfishThe common goldfish is a great fish for beginners since it’s a very hardy breed of goldfish. It can live in water with temperatures ranging from 55-80*F (12-26*C), with a pH of 6-8, which is much like tap water. The common goldfish doesn’t require a heater and needs only minimal care if placed by itself in a well filtered 10-gallon aquarium (38 liters). In the wild, you can find these in freshwater, lakes, rivers, canals and even ditches that have adequate vegetation. This water can be slow moving to stagnant. They do best in cooler water around the low 70s.Goldfish are however social animals and would benefit from having a tank mate. You can keep two of three small goldfish (a few inches or less) in a 10-gallon tank but when they mature, you will likely need to upgrade your tank size. A goldfish that is properly cared for can live for well over five years (40 years plus max) and grow to around 12 inches long, 32cm (4 inches average, 10cm).A small one-gallon goldfish bowl (3.7 liters) is not highly recommended. When you place a goldfish in a small space like a bowl, the water gets dirty fast and make the goldfish unhealthy. Read the next post for beginners: goldfish bowl size for more info. If space is an issue, consider buying a fancy Beta fish or cold-water minnows which will do better in a small space than a goldfish would.A Beta needs good water parameter too but it also has the ability to breath oxygen through its mouth in addition to breathing through its gills. This just means they can live in stagnant water with low oxygen levels much better than other fish species. Even with this species, you will still need to perform routine maintenance to keep them healthy and happy.

The Comet Goldfish, thought to have originated from the state of Washington in the late 1800s, comes in several variations, the most popular being the orange metallic comet whose color shows well in goldfish ponds. Other variations come in an array of calicos; calico varieties like the red and silver sarassa comet. Many of the color combinations come in colors like red and white, black and orange, yellow, red, black, and of course goldfish orange.comet goldfishThe comet goldfish is similar to the common goldfish types and is often mistaken for it, but the comet has a more slender body with more noticeable and elongated fins; especially the caudal fin, which is more than half to three-quarter the size of its own body. The caudal fin will also be much more pointed on its ends compared to the common goldfish. The comet goldfish will also have two pectoral fins and pelvic fins; while the dorsal fin, anal fin, and caudal fin will be single.

The shubunkin goldfish comes in two varieties (London shubunkin and Bristol shubunkin). Its body looks much like the common or comet goldfish, but its colors resemble that of what you would find in a fancy goldfish type. It has one caudal tail fin, one dorsal fin, and paired pectoral and pelvic fins. The Bristol is larger, and its caudal fin is more rounded than that of the London.shubunkin pond goldfishThe color of the shubunkin goldfish should be calico. 25% of its color should be a blue-silver color that acts as a background for its other body colors. An even coat of strong black dots and colors that run into the shubunkins fins is the desired look for show goldfish. Both the London and Bristol variety is one of the hardier types of goldfish. This makes it an ideal goldfish for an outdoor pond or an indoor goldfish aquarium. If you do choose to stock your tank or pond with shubunkins, avoid mixing them with the slow-moving bubble eyes or celestial goldfish. The faster-moving shubunkins will out eat these other goldfish types which could lead to them being starved.

The wakin goldfish is a popular breed in Japan. It’s thought to be the common goldfish of East Asia. The Wakin goldfish resembles the comet goldfish with an elongated body but has a double caudal tail fin much like the fantail goldfish, only shorter. Only the wakin and jikin goldfish have an elongated body and double anal and caudal fins. The wakin goldfish is a hardy breed that is best placed in a goldfish pond. If it’s placed in a goldfish tank, the tank should be large enough to accommodate its growth of over a foot long (30cm). It’s not an aggressive goldfish breed but is a fast swimmer with a big appetite and so the wakin goldfish isn’t a good tank mate for any slow swimming goldfish breeds. the appetite of the wakin goldfish can be a problem if the tank or pond contain live aquatic plants that it finds tasty. The most common colors of the wakin goldfish are a solid red or a variegated red and white color. The ideal balance of red and white colors should be half and half, but some goldfish might only contain a few small stripes of red on an otherwise white body; or vice versa. The reds should be deep and colorful, great for a goldfish pond. Other colors include metallics or variegated: oranges, yellows, browns and blacks.

Japanese Ryukin

ryukin Japanese goldfishThe ryukin goldfish from the Ryukyu Islands is a popular goldfish bred in Japan. It looks similar to the fantail goldfish but stands apart with a prominent hump towards the back of its head which elevates the dorsal fin. The long caudal tail fins can have three or four lobes, with the three-lobed ryukin having what the Japanese call a ‘cherry blossom petal tail.’ There are several goldfish types of ryukin, the yamagata kingyo, sabao, and tamasaba that have been bred to only have a single caudal tail fin. Ryukin goldfish come in a variety of color combinations, including: solid colors (self-colored) and multiple colors (variegated) of a deep red, red and white, blue, white, calico and more. A hardy variety of goldfish, the ryukin can be placed in your outdoor goldfish pond or introduced into a goldfish aquarium with other goldfish without any need for extra care. Good tank mates include the oranda, lionhead, or Ranchu Goldfish. Be careful that your bubble eye, and telescope goldfish breeds are not being bullied around by these tougher breeds.

Fancy Fantail

The body of the Fantail Goldfish should be about three-fifths of its overall length and have an egg shape appearance. The only single fin on the fantail goldfish is the dorsal fin; all other fins are paired, including the caudal fin which is split down the middle with a forked appearance on each fin. Regardless of the fantail’s fin, all are sturdy and rounded at the end to resemble, what else, blades of a fan. This is most noticeable when viewing the caudal tail fin from directly above.fantail goldfishFantail goldfish come in an array of colors from metallic self-colored (single color) to a variegated (multiple colors), including calico. The color of the variegated variety should extend into the fins and the calico variety should be mainly blue with patches of other colors. Colors of the fantail goldfish usually come in a few solids or a mix of orange, blue (silver), black, bronze and red. A good quality fantail will have a good balance of color on both sides of its body. While the fantail goldfish is included in the fancy goldfish variety and often bred for show, they are a very hardy species and are an excellent choice for beginners or for your outdoor goldfish pond. With the right care, your fantails can live for more than ten to twenty years. At maturity, the fantail can be six to eight inches long.

vailtail goldfishThe veiltail goldfish is a popular type of goldfish among collectors and hobbyists but it a variety that is difficult to breed for showing. It’s long flowing paired caudal is the veiltails most prominent feature. the caudal tail fins should not be forked or have pointed tips but be completely divided while viewed from above. When your veiltail goldfish swims, the caudal tail fins should flow elegantly in the water. Its dorsal fin should not fold over or sag but rather it should sway like a flag in the wind. The pectoral and pelvic fins should be long and narrow. Color-wise, the veiltail goldfish can be metallic self-colored (solid), variegated (multiple colors) or calico in color. The colors should strong and run into their fins.This goldfish type is not as hardy as the common, comet or ryukin goldfish but it can survive in an outdoor goldfish pond if the conditions are not too extreme. Most goldfish owners will choose to place their veiltail goldfish into their indoor aquariums.

Globe Eye or Telescope

The Telescope Goldfish or globe eye goldfish as it is known in Europe and dragon fish in the far east is a fancy goldfish type. Protruding eyes that begin to develop around six months of age clearly explain the name of this fancy goldfish breed and make it easy to recognize if a goldfish is a telescope. A high-quality telescope goldfish has good symmetrical placement of its two eyes, each located on the outermost tip of its globe shaped protuberance. The body resembles that of the veiltail goldfish, with a short deep rounded body. Aside from the single dorsal fin, all the telescope goldfish’s fins are paired and pointed, including the caudal tail fin. The dorsal fin is high on the back with a slightly elevated appearance similar to the ryukin goldfish When the telescope goldfish swims, the dorsal fin should sturdy and upright.

telescope bubble eye goldfish

The fully divided caudal fins should be about three-quarters the length of the body of the telescope and forked about a quarter of the overall length of the caudal tail fins. When it swims the caudal tail fin should be flowing like the oranda goldfish. The telescope goldfish comes in a variety of colors: all one color (self-colored) of red, blue, chocolate, or white; bi colors (variegated) of black/white and red/white; and calico. The calico types should have a blue background with a good symmetrical balance of bright brown, orange, red yellow and violet patches, with small black spots over its entire body. There is a variety that is named a panda butterfly telescope since its colors are predominately black and white and there is also the popular broadtail moor or black moor goldfish. The telescope goldfish is hardy and can survive in cold waters, but it really should not be kept in an outdoor goldfish pond. The main reason is that is has poor vision and can’t compete with other goldfish types for food. Another reason, which also has to do with their protruding eyes, is that telescope goldfish eyes are susceptible infection and injury. Make it a rule to only place these goldfish among other slow moving or delicate breeds.

Broadtail Moor

The broadtail moor goldfish or more popularly known as the black moor, should be entirely black (self-colored) throughout the body and fins. However, more often than not it contains shades of brown or silver. The color of a show quality black moor is a flat sooty color.black moor goldfishThe black moor closely resembles the veiltail goldfish. The single dorsal fin should be high on the black moors back; all other fins should be paired. The paired and flowing caudal fin should be fully divided with rounded tips and have an absence of a forked appearance. It differs from the veiltail goldfish types in that the black moor has protruding eyes that resemble the telescope goldfish. A show-quality black moor will have its eye placed on the extreme tips of its protuberances. It’s this style of eye that gives the black moor poor vision and is the reason you should avoid placing them into an aquarium with the more agile breeds of goldfish; they will out-compete the slower eating black moor goldfish.

oranda goldfishThe Oranda Goldfish variety is one of the fancier types of goldfish, making orandas one of the more difficult fancy goldfish breeds to take care of. They don’t do well in waters with a temperature less than 65 degrees which doesn’t make them suitable for your outdoor goldfish pond. It is best to place them in your goldfish aquarium with other slow-moving fancy breeds and a few aquatic plants. Due to its body shape, oranda goldfish are slow-moving and should be feed a balanced diet to keep it from having swim bladder or constipation problems. Breeding the oranda goldfish is another challenge for goldfish breeders. It is difficult to determine the sex of orandas out of mating season but typically, males are smaller and slenderer than females. During mating season, it is easy to sex them; males produce white dots on the hoods on their heads. (Don’t mistake this for goldfish ich.) If breeders are successful in mating two oranda goldfish, it is rare to get high quality fry. A high quality oranda goldfish will have a short deep body, about two thirds of its body length. The dorsal fin should be up high on its body much like the ryukin goldfish. All other fins should be long flowing and paired. The caudal should be divided and flow gracefully like the veiltail goldfish and have slightly squared trailing edges. Depending on which geographical location the oranda was bred, its caudal tail will look different. For showing purposes, the caudal tail should be deeply forked in the far east, but points are deducted for this in the west. An oranda goldfish is easily recognizable by its soft wart-like hood cover around its head. As they mature these hoods should develop around its head and face. Some orandas will develop more and some might not develop any. A good hood will have lumps of similar size that cover the entire head back to its gills. The colors of the oranda goldfish are varied: metallic, solid (self-colored), multiple colors (variegated) or calico. The redcap oranda goldfish should have a deep red hood and a silver body. Other colors include black, blue, chocolate, reds, and silvers.

The pearlscale goldfish with its spherical body shape and dome-like scales containing calcium carbonate, looks like a golf ball. The calcium carbonate in the scales creates a pattern of little pearl-colored domes pushing through the skin of these goldfish types. It’s what one might imagine a goldfish would look like if it swallowed a golf ball whole. The small pointed head containing a little mouth is not flashy and only makes the body of the pearlscale goldfish stand out even more like the most noticeable feature.pearlscale goldfishThe single dorsal fin stands erect, start at the middle of the back and extends all the way to the caudal peduncle. All other fins are paired with rounded ends. The sturdy caudal fins of the pearlscale goldfish should be divided and the lobes mildly forked. As the goldfish swims, the upper lobes on the caudal fins should sit high and not drop down. The paerlscale goldfish comes in a range of colors including: metallic self-colored and variegated (a solid color or two distinct colors); calico which should be strong and balanced. This hardy bred can live in an outdoor goldfish pond but are best suited for aquariums where their unique features can really be put on display.

Hama Nishiki Goldfish

A cross bred between the pearlscale and the oranda. This goldfish bred looks a lot like the pearlscale, but its fins are slightly longer, and it has a small wen hood cover on top of its face that it gets from the oranda. It also grows slightly larger than the pearlscale.

A ranchu goldfish is a full-bodied fancy goldfish that lacks a dorsal fin and has wen hood cover much like the oranda. The back of the ranchu should have a pronounced upward arch where it curves sharply downwards at the peduncle and caudal fins. This curve directs the pair of divided caudal fins downwards. The optimal angle of the back curve and the direction of the upper lobes of the caudal fins should be 90*.ranchu goldfishOne of the most obvious features or lack thereof on a ranchu goldfish is the absence of the dorsal fin. A show quality specimen should have a clean arched back; there should be no sign of a dorsal fin, whether that be a bump or depression where the dorsal fin might have grown. The ranchu’s wen hood cover should be larger than that of the oranda. It should cover the entire head and face but not the eyes. A full wen hood cover can also cover the cheeks and gill covers and resemble the mane of a lion. The Chinese version of the ranchu is called the lionhead for this reason.The ranchu goldfish from Japan and the lionhead goldfish from China are virtually the same breed with only minor differences in appearance. The back of the lionhead goldfish type lacks a serious arch and the curved peduncle is nonexistent. This allows the caudal fins to be more upright instead of being pointed downwards. A ranchu goldfish can be a metallic self-colored orange, red-and-black or a variegated multiple color, usually red and white. There are red-and-white nacreous varieties that give it a mother of pearl color called ‘sakura nishiki’ and there also calico nacreous colored ranchu goldfish that are called ‘edo nishiki’.

The pompon goldfish is named after its most obvious feature, its fleshy lobed nasal septa that resemble pompons. These growths are connected to the goldfish’s nasal septum and act as sensors for smelling airborne chemicals and odors. When fully developed, the pompon lobes can hang down into the mouth of the goldfish but in a quality specimen the pompon lobes should not hang down into the mouth. They should have a solid uniform growth and be spherical in shape. The body of a true pompon goldfish should look like the body of ranchu types without a dorsal fin. There are however breeds that have a dorsal fin or show signs of a wen head cover. Pompon goldfish come in metallic and calico colors. Pompon goldfish are best suited for goldfish aquariums with water no colder than 55*F and should not be placed in an outdoor pond. Tank mates should only include other delicate and slow-moving breeds like the telescope, oranda, bubble eye, or celestial.

Bubble Eye

The bubble eye goldfish has a similar body shape, fins, and upward pointing eyes as the celestial does, but it also has two fluid filled pouch of skin on its cheeks. A high-quality specimen will have two equally developed pouches that sit right below its eyes. As a bubble eye goldfish swims and changes direction, its pouches will bounce around and play catch up to the last move. The colors a bubble eye goldfish comes in are metallic self-colored, variegated, or calico.bubble eyeThe thin skin that makes up a pouch is delicate and requires special care to ensure it is not damaged. Considerable thought should be put into what types of substrate, aquarium decorations, aquarium filters, lights and tank mates the bubble eye goldfish’s tank is filled with. With the presence of these pouches, upward-pointing eyes and along with the lack of a dorsal fin, makes the bubble eye goldfish a slow swimmer with poor eye sight. Avoid any aquarium decoration or substrate that contains sharp edges. Place any air bubblers in a corner and out of the way of where the bubble eye goldfish swims. Choose a filter that doesn’t have a strong intake or one that creates a strong current. Buy low wattage aquarium lights. Only place a bubble eye goldfish in with other poor seeing and slow swimming goldfish breeds like the celestial, pompon, ranchu or telescope.

— Back to Top —


Celestial GoldfishThis small and delicate fancy bred of goldfish has a unique feature that needs special care to ensure the goldfish’s health, making it not suitable for the beginner goldfish hobbyist. The eyes of the celestial goldfish are protruding and set to always face upwards. This feature means the celestial goldfish should not be in a tank with any decoration that can scrape or poke its eyes. The goldfish tank should not have a bright light since the celestial goldfish is always looking up while at rest. The celestial goldfish lacks a dorsal fin and when it swims it pushes its head downward to see straight ahead. This lifts its body and caudal fins upwards, making it a slow swimmer and not suitable for a tank with a water current. Tank mates should only include other celestial goldfish, bubble eyes, pompons or telescopes.

  1. How many fish can I put in a 21.5 across , 36.5 width and 25.7 tall tank( I have guppies and shrimps)*・゜゚・*:.。..。.:*・'(*゚▽゚*)’・*:.。. .。.:*・゜゚・*

  2. I’m not so sure what type of goldfish I have ,so please can someone help me?we have two fish that are oval shaped, with orange skin and scales, and has like a type of black dots that looks like a smiling face if you look sidwards.
    Thanks for your help,

  3. I have a black and gold goldfish and it has a beautiful black fantail very rare I can find a example , what species is this.

  4. I have a telescopes goldfish that was sold as a butterfly goldfish, his tail only has three fins ,is this a true butterfly .His tail looks nothing like the others.

    • The answer is a resounding YES. Just make sure you have a large enough tank for them. If you want to grow them out some in a smaller tank that’s ok(they kinda look lost in a big tank and is what I do). MAKE SURE YOU HAVE A TANK THAT’S A MINIMUM OF 55 GALLONS WAITING for when they start to out grow their tank. The idea that a fish will only grow as large as it’s tank is FALSE.
      Remember that Oranda’s can get larger than the average female hand not including the fins. Try to get a filter that’s at least twice (min) recommended for you goldfish. (i recommend it for any tank actually)
      as goldfish produce a lot of waste. They like nibbling on greens so toss some common floating plants in for nibbles.
      BE SURE TO HAVE A HEATER. Ones that are completly submersible and stick to the side of your tank are best.(you may need morw than one depending on what your store offers but it’s worth it). Partial water changes are vital.
      Yes, they can be a pain in the but to care for properly but so are other fish. Enjoy them! Love them! And you will have them for many many years.They are a very personable fish. (at least mine are). Good luck and may you be rewarded with their beauty for many, many years!

    • If you are looking for just a common comet you can go to the pet store and look at their “feeder” tank. When requesting a certain colour most will oblige. They shouldn’t cost more than 25 to 50 cents each. I recommend buying at least two so they have company.
      Please tell me they’re not going a bowl but something like a 10 gallon tank. Enjoy you fish!

    • Check the pH levels in the tank. My two goldfish thrive in a 7.6 ph level but I’ve noticed some goldfish like other levels. Nothing more or less than a 6-8 though. If you also don’t have oxygen and a filter in the tank they can be suffering from excess ammonia in the tank. Stress can be a factor as well in fish, so if the tank is too small (20 gallons minimum for one fancy + 10 gallons for another fish) it could be causing stress for them as well. Flake food is bad but I’ve noticed if you put it in the filter stream they will have fun chasing the food around the tank! I recommend pellet food and feeding them at least a green pea once a week so it prevents dropsy. Goldfish have their intestines all scrunched up in their chubby bodies! So sometimes if some air or too much food gets stuck up in there, they can’t control themselves on their swimming features. Just make sure your goldfish are healthy and do your research!

  5. Do you have to have a male goldfish if you only have one female goldfish that’s pregnant? I found out earlier that my one female goldfish is pregnant. Do I need to get a male goldfish?

    • Only if you want babies. They may be eaten by the parents as eggs or small fry so that may not be a problem for you. I do recommend however that she be given a companion of either sex

  6. Hello I have a fish calico Japanese ryunkin fantail with 2 balls on his shoulders behind his gill covers x after keeping fish for 50 yrs I have never seen anything like x

    • Man o man! You just described one of my fish sold to me as a fantail! I thought it has tumors. Glad to hear that’s normal.

  7. I have a comet and a moor unforunately my moor died today and now my comet is just sitting at a corner , is there any fish you can suggest i can put in tank with my comet so that my comet can pair with it. My existing comet is a male.

    • Well, it usually isn’t a good idea for comets and moors to be together, but you made it work I guess. Don’t attempt it again though.
      You could pair him with any GOLDFISH of similar size and speed. Speed is important because the fast fish always get all the food first, making the slow fish starve. Goldfish are only compatible with goldfish though so only get another goldfish, but make sure it’s fast, of similar size, and has no delicate body parts like a celestial, moor or bubbleeye.
      There you go, Omar. Good luck 🙂

      • I have had different varieties of fancy goldfish with many different varieties of cory cats for about 17 years. I have never had a problem with large fancy goldfish picking on my cory cats regardless of the huge difference in size. I never knew I could combine fancy goldfish with cory cats until an aquarium store employee told me that I was able to do that. I love having the variety.

    • My comet goldfish is attacking my black moor, I unfortunately had to take him out and put him in a bucket. They are predators and should not be with black moors!!! He is trying to kill my poor gold fish! 🙁

      • I have a black moor and a comet living together currently. They’ve been doing well for 3 months now and both seem very happy. There has been no sign of fighting or illnesses for me.

    • I have a comet goldfish (Ori) and a black moor goldfish(Rexi) living together for about 2-3 months now. I don’t know which one is male or female, but I suggest checking the pH level in your water. Make sure the tank is 10 gallons and above because they both can get pretty big. Have a lot of decorations (but not too much) like gravel, plants, a little house, a live plant, etc. Make sure that your fish/fishes don’t have an illness too. Hope I helped! 😀

    • Fish can and do get depressed when losuming a tankmate especially if they have been together for a long time.
      It doesn’t matter what sex you get but I would definatly get him a new tank mate or 3. (it’been my experience that they do better in even numbers so after the adjustment period obe is not left left out of the group).
      I’m very sorry to hear you lost one of your babies today. 🙁

    • hmm, any other symptoms? im only 20 but i love goldfish. i might know its issue. is it laying at a angle? or gasp for air? also do you know the species? if its a fancy or fantail it could have bladder issues or may be bloated. if not it might be nitrate poisoning. all you need to do is change 3/4ths the water is balance in the tank once every seven days till the bacterial cycle and nitrate cycle is balanced again. if its swim bladder, try feeding the fish skinless freeze dried peas. hope this helps.

    • sometimes the stress of another fish dying in the tank can actually cause the other fish to get sick or die too, its like they put off some sort of energy waves when a fish is ill or dying and it can be contagious to other fish in the same tank

    • Goldfish are sometimes known to have a rest period at the bottom of the tank usually because of stress, weariness, or irregular feeding, but it is nothing serious usually.. It’s not dead though as your fish will float belly up when dead.. Sometimes fish will go to the bottom when injured, but be patient and monitor the fish’s behavior carefully.. I have two goldfish of my own in a tank with a divider, and they each often go to the bottom for a few hours once every 24 hours or so.. if that is the case then your fish is probably resting which is normal.. So I wouldn’t worry if I were you..

    • My black moor is doing that too since I removed the comet goldfish. The comet is trying to kill him so I had to remove him and put him in a plastic bucket. Sad!

  8. I have 1 black moor fish and I want to know if I can get other fish to go in the tank with him? What other breeds of fish can I put in the tank with him?

  9. Hi I have a big common goldfish and 2 gold fantails in the same tank ,the big gold fish keeps chasing the bigger of the fantails and pins it to the side of the glass or on the bottom of the fish tank,should I take the big goldfish out of the tank.

    • If they are different breeds of goldfish, they are very unlikely to breed. Common goldfish only breed with common goldfish because they are already a different species and cannot mate with other goldfish species. You will not get an output at all; best to try to breed one species or the other.

    • It is usually chunky on one side and often looks asymmetrical, and when the “pregnancy” is about to end (for it is not a pregnancy but a storage of eggs of that which do not hatch immediately and live), males will chase it and pin it so it lays its eggs.

  10. I buy gold fish But it’s kind a. Different
    Black color on his head to towerds to is fin

  11. Hey!
    I have a pond in my garden when we built it we bought 5 comet Goldfish they are big now and 3 of them have very long tails but 2 of them look more like a common goldfish. They started breeding last year and now we have about 45-60 fishes in the pond in all sorts of colors and 2 black telescope goldfish, Can the comet goldfish breed telescope goldfish, or how did this happen ?

    Will they stop breeding, when they are to many? (They all look healthy and are friendly with each other)

    My largest comet his body is maybe 175mm and long tails. He has bumps on his head, he had them for two years now. No other fish has bumps. He swims fast eats and are just like normal. What can it be, is he sick ?

    • If you really know that one of the goldfish was a “he”, then it you would see that male goldfish tend to have bumbs on their head while females do not.

  12. I would like to know do you think the background of my tank makes a difference? Should I change the background photo here and there if it does matter?

    • If your fish is swimming sideways or upside down then your fish likely has swim bladder disorder. The swim bladder, while working properly, helps a goldfish control its buoyancy. If you notice that your fish starts swimming upside down a few hours after eating, it was most likely caused by constipation (but could also be a result of infection or enlarged organs). Overfeeding your goldfish or feeding your goldfish flakes can lead to this issue. You can try witholding food for three days or feed your goldfish a cooked pea (make sure you peel it cut it up). In my experience peas have always worked.
      Make sure you’re doing regular water changes, and maybe try switching your goldfish food (sinking pellets work great for my goldfish).

  13. Hello,
    I have a 3 comet gold fish in fish boule. I just want to know this is good for them. And how many days after i want to chang water. And how many times food given per day and how much like 1 tabel spoon, 2 spoon.

    • Three goldfish in a bowl will require you to change the water daily. in terms of feeding, 3-4 or so flakes per fish, 2-3 times a day (all food should be consumed within a min – any longer and you overfed them). It’s recommended you upgrade to a much larger fish tank with filtration if you want the goldfish to live a long healthy life.

  14. I have 6 goldfish! And I know the breed of 4 of them but the other two confused me, one of them is silver/blue? And the other is black but doesn’t have telescope eyes so I guess it isn’t a black moor? Idk

  15. Sir pls reply my orandas head i mean their hood was nipped by the other goldfish will it regenerate themself? I mean the hood will it be back to what it was before?

    • I’m not an expert on this matter so I am not entirely sure if it will regenerate fully though – though it should continue to grow if the goldfish is still young. Depending on how bad the injury was, it might not be noticeable over time. But the real issue here is will your other fish continue to attack it. If they did it once, they will likely continue to do so. You might want to separate them by giving the Oranda it’s own tank or by removing the instigators from the main tank.

  16. Hello, as a gift I was given two comet gold fish today. I already own a telescope eye goldfish but I’m not sure weather I should put my comet goldfish in the same bowl as my telescope eye goldfish. I know that they shouldn’t go together because the telescope eye fish is slow at swimming due to it’s heavy body but I have no where else to put my new fish besides a small bowl, which is clearly too small. What should I do?

    • You should really consider finding a big habitat for your goldfish. Three goldfish in a small bowl would need their water changed a few times a day. That doesn’t seem like a good solution. In regards to having live in the same bowl as the telescope, you can see how they act during feeding. If the telescope is able to eat a fair share of food, it’s probably okay to keep them together. One other thing to worry about is to make sure the comet goldfish are not nipping at the telescope.

  17. I have a pearlscale and a small calico telescope goldfish. I just purchased them today and the telescope keeps running into the pearlscale and nibbling at it. So far the pearlscale won’t eat anything. Should I just wait it out or do I need to take one back and get a goldfish more similar to the pearlscale?

    • You might want to add a few decorations into the tank to give each their own space. a bit of chasing is fine but obviously not constant chasing.

    • They can grow to around 5-7 inches perhaps. It all depends on the size of the tank, the quality of water, how much you feed them and a few other variables. I don’t think it matters if you buy from PetSmart in terms of how large they will grow.

  18. Can a fancy fantail gold fish be in the same tank as the Ryukin goldfish? I sse then chasing each other but when I went to the pet store they told me all goldfish can be with other goldfish?

    • Technically they can live together but sometimes there might be little issues like this. Is it a real issue? – it might not be. If the goldfish being chased isn’t constantly being chased and its fins are not being picked at, it will probably be okay. By adding a few hiding places or some plants to break up the visibility in the tank, the two goldfish will be able to stick to themselves more easily.

      The real problems occur during feeding. If you add a fancy slow moving goldfish in with a more common species of goldfish, it might not be able to compete for food as easily. As a result the faster common goldfish will get all the food and grow bigger much faster than the fancy goldfish.

    • If you can, we would recommend that. Then try adding some aquarium salt. It could be an issue with the swim bladder or a digestive issue. Also try not feeding it for a day or two. This might help too. If the issue continues, look through all the posts on the different goldfish illnesses to help you determine what the problem might be. Let us know how your Oranda is doing in a day or so.

    • It might be normal but it might also be a sign they are sick or the water quality is bad. If they are new to your tank, it’s normal for them to be inactive until they feel comfortable. You can test the water for ammonia or ph to see they are good and if they are off, do a water change. Review our goldfish diseases section to see if your goldfish show signs of an illness.

  19. hi, im austin you need to put 5 or 6 goldfish in your tank because you need to leave room for them to grow and when they get up to 6″ inches you need to put them into a bigger tank or you will cause diseases.

    • The biggest cause of death to goldfish is poor water quality. Make sure the ammonia levels are low, the ph is neutral and there is a lot of oxygen in the water. You can purchase inexpensive test kits to test the water quality.

    • The only real good tank mates for goldfish are other goldfish. The reason being is that goldfish like cold water (unheated) and they are also aggressive eaters. Many fish can’t live in an unheated tank or move fast enough to compete for food. You could try certain cold water minnows perhaps.

    • The basic rule is one fully grown goldfish per ten gallons but a lot of people put two or three small goldfish into a ten gallon tank. As they grow you might want to upgrade your tank size. They are social creatures and do like the company of other goldfish by the way.
