Bubble Eye Goldfish
The Bubble Eye goldfish has some of the most unique and interesting features of many of the other types of goldfish. Bubble Eye goldfish are relatively small in comparison to some other breeds, having metallic scales and a characteristic “double tail”. They don’t have a dorsal fin, but this is not the most unique feature of this special fish. Bubble Eye goldfish are so named because they have two pouches of skin that are filled with fluid, located just below their eyes. These fluid sacks are not present in young Bubble Eye goldfish until they reach about three months of age. However, after this time, the eye pouches will continue to grow into the fish’s adult life.
In reality, the fluid pouches on the Bubble Eye goldfish are extremely fragile. When kept in an aquarium, it’s highly recommended that you avoid placing any sharp or abrasive decorations that could damage the Bubble Eye goldfish’s fluid pouches. In addition to this, the Bubble Eye goldfish may be prone to injury from the attentions of other more aggressive breeds of fish. Since the Bubble Eye goldfish only grows to a length of about 6 or 8 inches, it may be a bit smaller than the other fish in the tank.
Bubble Eye goldfish are similar in appearance to Celestial Eye goldfish. They have a consistently curved back body shape, which is bare of any fins or distinguishing markings. When healthy, the cheek pouches of a Bubble Eye goldfish will be even in size.
