Wanju Fish       Bubble Eye Carassius auratus                             The Bubble Eye is a small variety of fancy goldfish with upward pointing eyes that are accompanied by two large fluid-filled sacs. It is a dorsal-less fish, and good specimens will have a clean back and eye bubbles well matched for colour and size. The bubbles are fragile and the fish should be kept separately from boisterous types and away from sharp tank decor, although the bubbles will regrow if punctured. Given proper accommodation, the bubbles do not disadvantage the fish and they become very tame. It is known as suihogan in Japan.
