mine is worse, the peaople at petsmart said it started a little while ago so now i think it is dropsy/bloat...
It wont hurt to just feed it peas. Its good for fish regardless. I thought dropsy kills within 24 hours though. If it started a long time ago (more than a week) it can't be dropsy. Try the shelled peas, its worth a shot. I personally think its constipated but I'm no expert.
What should i do????
