Hey guys, despite all my efforts and research, my betta just won't heal up from a moderate case of fin rot he had a few months ago. I thought I had it worked out, as he started growing fin back about two weeks ago. However, in the last two days, he's lost (in chunks, not all over) everything he has grown back, and maybe more.
The tank is new, and I'm relatively new to betta fish, but I've had a 10g community tank set up and running for most of my life, so I do know quite a bit about keeping fish in general. While the tank was cycling, I had him in a 1g bowl which I did 100% water changes every two days. He had a mild case of fin rot when I brought him home from the store. He healed up in no time, and looked as he does in my profile pic. I made a bad decision to put him into his personal 5g before it was fully cycled, and the fin rot returned. So, back into his heated 1g (sticker thermometer said 78F relatively steady). The fin rot stopped getting worse, but it was not getting any better. During this time, the 5g had finally cycled. Eventually, I got tired of changing the water every day when he had a fully cycled, properly heated, planted tank just sitting empty, so I slowly acclimated him in his cup, and put him in. He immediately darkened up, and looked extremely happy. In the morning, he had about 1mm of new fin growth. I can only assume the small heater in the bowl, and the sticker thermometer were incorrect and he was too cold to regrow the fin.
However, now he is losing fin again, and the water is pristine. I really don't understand. It definitely does not look like he's biting because it's being eaten away around the rays in his tail before those finally go away as well. I'm going to attach some pics to show. Ignore the difference in color from my profile pic, these pics are from a much better camera. He is actually the same color as before.
