The Bubble-eye Goldfish, also known as suihogan in Japan, is a breed of "fancy" goldfish with large fluid filled sacs beneath its eyes. Due to its unweildy, unnatural appearance, much controversy surronds the breeding of this fish. Many claim that selective breeding has turned the Bubble-eye strain into a species unable to survive in any environment other than the aquarium, and this selective breeding should be stopped. On the other side of the controversy, advocates for the breeding of Bubble-eyes and other "fancy" goldfish say that in the hands of a responsible owner the fish leads a quiet and fulfilling life, not having to compete for food at all.
Physical description
The enlarged fluid-filled sacs beneath the eyes of this variety of twintail are highly distinctive, and they sway as the fish swims. The rest of the body is roughly egg-shaped with a straight dorsal surface. The coloration varies but is usually metallic red-orange. The dorsal fin is absent and the anal and caudal fins are doubled, the extravagant caudal fin flowing from a down-turned caudal peduncle.
History
The Bubble-eye Goldfish variety was first developed in 1908 in China, although there is evidence to suggest they existed in the eighteenth century.
In the aquarium
The eye sacs are prone to damage, so it is best to keep this strain in its own aquarium, without sharp-edged furnishings. Like all twin-tailed varieties, Bubble-eyes are not suited to pond life, as they will not be able to compete for food with faster fish. Furthermore, the Bubble-eye should not even be kept with other twin-tail varieties, as the eye sacs impede its movement so much that it won't be able to compete with even the slowest of rivals.
