A young male Sawbwa I bred last year has recently hit a bad patch. All colour has pretty much gone, the stomach has shrunk in, and fins are clamped. I do have a spare 10L tank that I can use for quarantine/medication available, as I can't treat the whole tank, as shrimp and snails inhabit it as well. I'm now wondering if I should try a course of medication or remove the fish and humanely euthanise it. If I were to give it some medication, what would be the best to go with? I did have some fish a couple of years back be infected with FishTB; however they had heavy breathing issues, while this one does not.
You can see the difference in colour between my eldest male and this fish in the 1st pic.
