I recently got a new betta about 2 months ago. He is in a 5 gallon tank with a heater and filter. After about 2 weeks of getting him, my small 5 gallon tank recycled, causing nitrites to spike. Around this same time, I noticed my bettas fins starting to appear ripped. I suspected fin rot, although I'm not sure if he is biting his own fins. They will tear and appear to slightly regrow and then tear again. After doing daily water changes, I have finally gotten my tank fully cycles, although his back fin appears ripped up again when I came home today. All of my parameters are good. Do you think this is fin rot or my betta biting his own back fins. I have attached a few pictures showing what it looks like.
