Tough call, hard to treat this in a planted tank. Might think of moving him to a hospital tank, treating and then after the fish is better, add him back to the community tank.

Thanks Eddie, I'll try to get a picture posted when I get back home. Would a salt dip be a good start until I can get him in hospital tank?
