I think my betta has fin rot. He keeps getting red spots on his fins, his gills are red on the inside, and his fins look shredded/have slices taken out of them in places. I've been treating him for two months. I take him out of his tank and put him in a hospital tank with 100% water changes. He always looks better after a couple days, and after about a week I put him back in his tank, and a couple days later he has red spots again.
I've tried treating him with Maracyn II and Tetracycline, and the spots just keep coming back. I took out the sand in his tank and put in gravel. I wiped the whole thing down with vinegar. I took off all the leaves on his plants that were brown at all.
What else can I try? Should I just keep him in the hospital tank longer this time? Or could something else be causing the problems?
