Roughly 2 1/2 months ago I picked up a halfmoon betta from the local petsmart. He seemed fine when I got him, but after about a month his ventrals almost completely fell off out of the blue, and right after that he got fin rot. I decided to start with the clean water treatment as I usually would. It helped him regrow his ventrals a bit, but the fin rot still hasn't gone away, his fins are beginning to get worse, and I'm getting a little concerned. Any reccomendations for treatment?
Sorry for the lousy pics, he never stops moving.
