I'm kind of at a loss here. I try to keep the tank as clean as possible, yet Ares's tail started fraying. At first, it was just tiny holes. Then, small tears and now, his tail is all ragged. Is it fin rot or is he biting his tail? I hadn't seen him biting it.
Sorry for the bad cellphone picture. Still sick and can't get my camera because moving around too much makes me dizzy.
