My poor fish Kai just got over his fin rot on his tail and I was admiring how lovely they looked, then this morning I noticed they were all ripped to shredds...I do have him in a split 2.5....but I don't think Ula (the other male) would have ripped off his fins....guess it's possible. I do also have some plastic plants in there with him, but I also have a piece of pvc pipe for him to lay in so he doesn't lay in the plants. Anyone have a personal/professional opinion as to what caused the fin shredding? BTW, he's very happy and blowing bigger and bigger bubblenests so I don't think it has anything to do with his tank mate.
