Hamster als Fische
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 – good specimens will have a clean back and eye bubbles that match in color and size. Their bubbles are quite delicate, so the fish should be kept separately from boisterous types, as well as sharp tank decor. Although the bubbles will regrow if punctured, an injury could leave the fish prone to infections. The bubbles can disadvantage the fish as it is not a strong swimmer, with a seemingly low bobbing head at times; bubbles are infamous for being sucked into filters and siphons in an aquarium.
