Hi, something is currently happening with my betta. About a month ago, his fins started to look frayed. There was no red or black on the edges or anything. So I started to do 50% water changes every other day. The fins continued to get worse. So I moved him into a smaller quarantine tank, and treated him with aquarium salt for 6 days. The fins continued to get worse. I am now doing 100% water changes every day in his smaller quarantine tank, but today one of his fins split in half. It's not all the way to his body, but the split is pretty long. I cannot tell you the water parameters of his actual tank because it is currently in the process of being cycled because I just found out about that. But it is 5 gallons and has a filter and heater. I really really need help. I'm really worried about him and I feel like I've tried everything but nothing is helping. I'm at a loss. Thanks in advance.
