I have a betta fish that I initially thought had just a fin tear, but progressed in to a pretty bad case of fin rot. I’m new to fish and it took me a bit to figure out anything was even wrong. I’ve been treating him for that for about 4 days doing aquarium salt baths. Tank parameters are below: Tank size: 10g and cycled Ammonia: 0ppm Nitrite: 0ppm Nitrate: 5ppm pH: 7.0 Temp: 78-79F I’m starting to think it’s not just fin rot that’s the issue. Today he developed these black spots on each side of his head that weren’t there before. He is still pretty active and has a good appetite. I don’t know how to help him at this point. The fin rot doesn’t seem to be improving with the salt baths.

If hes not improving, is he getting worse? If he is, then baths are not working. If the rot stopped, then its working.


He’s not really improving, but he’s not declining as fast as he was before. I’m beginning to think he has columnaris based on some of his scales turning white.


I'm no fish expert but I'd say follow some online instruction and use some medicine.
