After doing a month of aquarium salt and every other day water changes, my betta's fin rot was not improving as much as it should have, so I started him on kanaplex. Immediately I noticed his color got more vibrant and he became more active, and very slowly his fin rot is getting better. I see new growth. However, it is not completely better yet. There is one small spot on his fin that still has the dark edges. I've already done two courses of kanaplex (3 doses x 2). Is it okay to continue him on the kanaplex for another course or two? He is doing just fine on the medication, and I am worried that if I don't continue it, the fin rot will come back/get worse. I really don't want to mess around with it :(
What do you guys think, and has anyone kept their betta on kanaplex for longer than two courses?
