I don't know HOW THIS HAPPENED!!!! My betta Marc is in a 5.5 gallon cycled/heated/divided tank. There is absolutely NOTHING in his tank that possibly could have ripped his fins, NOTHING. Everything is very soft and there are no sharp edges on his deco. And there is no way he jumped the divider because Lorenzo is fine and Marc is still in his own side, plus Lorenzo isn't aggressive at all.
I left 2 hours ago to go see my boyfriend and before I left everything was fine.. when I came back Marcs fin (the fine that comes out of the end of him, not sure the name.. its not the one under him but the one at the end.) was tore to shreds! It doesn't look like biting because its so scraggly.. but there are chunks missing but I can't find any chunks in the tank... I am soooo freaking out.. He had a horrible case of fin rot when I first bought him and he grew at least 3cm of new fins that were GORGEOUS. He is my favorite so please help!!
Here are pics of before I put him in the divided...
And this is what I came home to...
^^ You can see all the beautiful re-growth on the fin at the bottom of his body in these pictures... his fins were perfect now look at them!
