Just today, i noticed that my bettas been acting strangely. Since I was in a hurry this morning(school has, after all, just started) I didn't check to make sure that he ate all or any of his food as i usually do. This afternoon, I saw that he constantly wedges himself under the lowest leaf of his fake plant and thus looks dead but i got him to swim out and around. When he does, however, his head dips down a little so he's swimming at an angle. Also, when he stops moving his fins(the pectoral i thinthey're called but I'm not sure--the ones on his sides) he starts to tip so that one side(not his head or back) is facing the bottom of the tank and the other is facing upward. Basically, he looks like he went belly-up only it's his side instead of his belly. The front-most area of his belly looks larger than it used to. He only recovered from fin rot about a week ago and his tank was cleaned on Sat., if any of you need to know. Does anyone have any idea what's wrong with him and how to treat it?
