The fins and tell of my betta seem to be frayed. I do not think it is rot due to the fact it is still the same color as the fish. It looks as though each strand or whatever of the fin ends on its own and is not one flowing thing. Also the top fin seems to have a peice hangin off the end of it. What is it and can it be treated or does my betta just need to mature. He is beutiful blood red except for the end of his fins and tail which seem to take away from his beauty.
