Moved my betta into the 16-gallon, because it makes him happy. Arrangements are in the works to get him a nice five-gallon for when school starts. Thing is, he's got an injury- I think a piece of the decor was too bristle-like. He now has a long cut along his back fin.
Approximately the length and location of the cut.
He doesn't seem to be in any distress over it. Behavior is still normal. But I wondered if it will heal/grow back? (I know that tails grow back after fin rot provided the infection doesn't get to the base and eat the fin completely... same deal?) If so, how long-ish does that process take?
I love my betta. I feel like a bad owner now T_T
