Hey everyone, I am a HUGE betta lover and have owned these beautiful fish since I was little. The male betta fish I have now, Lion Heart, has been with me since around January or February (I can't remember). About a month ago his fins got sucked up into the filter in his tank and were ripped to smithereens. I've been nursing him back to health and his fins have already fully grown back, but he's had eating trouble ever since. I feed him a little bit of flake food every other day, but somehow his belly is always swollen and he floats on his side and can't swim normally. I am worried about him, I tried not feeding him for a week thinking he might be constipated, but it didn't work. Is there anything I can do for him? Any help will be appreciated, thanks!
