i have a fantail that everv since i got him (Wilbur) he swims upside down on his side all over the place he eats and seems preety healthy but is he just goofy or is somthing wrong?

Bouyancy problems usually indicate a swim bladder that isn't functioning properly. This can be a symptom of a hundred problems ranging from "treatable" to "life-threatening."

If he seems otherwise capable of eating and doing other fishy things, he's probably okay. Do you find that he floats badly after eating? It may be a food-related problem. Be sure to feed sparingly and to pre-soak all food for at least a minute before feeding. In addition, add lots of green vegetables to his diet. Carp-derived species need lots of fiber in their diet to digest properly, so feeding things like spinach and broccoli help them move food through their gut easily and reduces stress on their swim bladder.

hello, sounds like he may have swim bladder problems which can be helped through feeding him peas. i would feed nothing but cooked shelled peas (frozen) for atleast a week. this will help him alot. let others have a chance to speak also before doing this they may have other ideas also do u use sinking foods to feed him? if you feed flakes try soaking them first for 5 minutes before feeding. sinking foods are much better and prevent this problem.

If it turns out not to be food related he may be suffereing from exposure to high nitreates which can also cause flipover. I have one fish goes ballistic if the nitrates go over 40, swimming errractically.

I soak his flakes and im starting to feed him spinach thanks for the help
