Goldfish Popeye DiseaseGoldfish popeye is a generic term used for an internal bacterial infection that causes fluid to build up behind the eye of a sick goldfish, making the eye bulge or “pop out”. Goldfish popeye is often the result of goldfish dropsy, an internal bacterial infection or goldfish tuberculosis. Both dropsy and tuberculosis are difficult to treat. Trauma might also cause a goldfish’s eye to bulge or even fall out due to swelling of the blood vessels. (see goldfish eye diseases for more goldfish eye problems.)

At first the eye or eyes of a sick goldfish will bulge slightly. As the goldfish popeye infection worsens, the eyes will appear popped out on top of fleshy bags of fluid. (looking much like a telescope goldfish.) These severely protruding eyes can be pick off by aggressive tank mates.
Most water treatments will fail to reach the internal bacterial infection and many water treatments are also hazardous to the biological filter; although an aquarium salt bath can help lower the osmotic pressure of the sick goldfish and help ease the swelling behind the eye. An injection of Baytril is an effective cure but injecting a goldfish with antibiotics should be left to the experts. More available treatments include Maracyn Plus Biospheres AntiBacteria Therapy from Mardel or Kanamycin (Kanaplex 5gm). Kanamycin is less harmful to the goldfish than Maracyn.

I just noticed that my goldfish’s eye was bulging outwards after a power outage. She’s always been a healthy fish, I purchased some fish infection medication for her. But I think it was from trauma. Even though she has been through multiple power outages

I have a 14 year old comet goldfish that has pop eye and cloudy eye. I have been treating it with melafix for 2 weeks and it is still not cured. I live in a rural area not near any fish stores. I have ordered pimafix and have just bought API aquarium salt that I have not yet used. My tank is 20 U.S. gallon. Any suggestions? Should I also use nutrafin aqua plus?
So first my oldest Goldie (3-4yrs) comes down with Ich, and now his eyes are starting to swell! Great! Is there any correlation with the two??

Why didn’t you do water changes?
is it contagious to other fish?
I have a koi pond but also have gold fish. One gold fish has pop eyes which occurred recently. Is this something that is contagious to the other fish?
Will the fishes eyes go back to normal?
Hi, my goldfish developed pop eyes and are both cloudy as well. He also keeps tipping over with head up and tail down. I believe it lost most of its vision since he isn’t swimming properly. What can I do to treat my fish? Will Melafix help?
In addition to the Melafix treatment medicine, try using some aquarium salt to ease the pressure. Additionally,test the water for ammonia, ph, nitrates, etc…and do a water change.
