Physical Characteristics

The pearlscale goldfish is renowned for its unique appearance. Its spherical body shape, resembling a golf ball, is adorned with domed scales made of calcium carbonate. This distinctive feature is what sets the pearlscale apart from other goldfish breeds. The small, pointed head, although less noticeable, beautifully complements the remarkable body shape. The single dorsal fin starts at the middle of the back and extends to the caudal peduncle, while all other fins are paired with rounded ends. The caudal fins are sturdy and should be divided with mildly forked lobes that sit high, maintaining an elegant posture as the goldfish glides through the water.

Color Variations

Pearlscale goldfish exhibit a wide range of captivating colors and patterns. They come in metallic self-colored varieties, where a single color dominates the entire body. Variegated pearlscales display a stunning combination of multiple colors, creating intricate patterns that add visual interest to your aquarium. Calico pearlscales showcase a vibrant mix of orange, red, black, and white, resulting in a kaleidoscope of colors swimming gracefully through the water. The color variations of pearlscale goldfish offer endless possibilities for creating a visually striking aquatic display.

Care Tips

To ensure the well-being of your pearlscale goldfish, it is crucial to provide them with a suitable environment and proper care. Here are some essential care tips to keep in mind:

Tank Size

Pearlscale goldfish require a spacious tank to accommodate their round body shape and allow them to swim comfortably. As a general rule, provide a minimum of 20 gallons of water per adult pearlscale goldfish.

Water Parameters

Maintain good water quality by regularly monitoring and adjusting water parameters. Pearlscale goldfish thrive in temperatures ranging from 65-72 degrees Fahrenheit (18-22 degrees Celsius) and prefer a pH level between 7.0 and 8.4. Additionally, use a reliable filtration system to keep the water clean and oxygenated.


Pearlscale goldfish are omnivorous, and their diet should consist of a balanced mix of high-quality goldfish pellets, flakes, and fresh vegetables. Supplement their diet with occasional treats such as bloodworms or brine shrimp. Be mindful of overfeeding, as pearlscales are prone to swim bladder issues and constipation. Feed them small portions multiple times a day to prevent overeating.


Choose tankmates that are compatible with pearlscale goldfish. Opt for peaceful and slow-moving species to avoid competition for food and potential injuries. Good tankmates include other fancy goldfish varieties such as fantails, ranchus, or orandas.


The pearlscale goldfish is a true gem among goldfish breeds, captivating enthusiasts with its unique spherical body shape and distinctive scales. By providing a suitable environment, proper nutrition, and good care, you can ensure the health and happiness of your pearlscale goldfish. With their enchanting presence and vibrant colors, these elegant fish are sure to become the centerpiece of any aquarium, captivating the hearts of all who observe their beauty.
