Hi everyone Im new here. I have been looking at the threads for a while and they have really helped me out. Im worried about Gill. His fins seem to be wearing away. He has one tear, on top I dont know how he got it. And the bottom and top fins look to be getting pointy. I worried that he has the beginning of fin rot. I do have a filter and I leave it on all day until night time, than I shut it down. It not very powerful. I do have that rock hiding place for him. I dont know if that is hurting him. It doesnt seem sharp. The water I change twice a week. 50% than 100% every three days. He does have a marimo ball with the help of your advice. and live betta bubs. he is in a 2.5 tank. If you look at my picture can anyone tell if it is fin rot? Its not a great picture Ill see if I can get another. he seems happy, swims, flashes, eats. Maybe its just me, a worried mommy.
