Long story short, I was given a 5 inch Pictus cat fish. His top spike fin and one side fin had become tangeled in a net, The top spike is stripped of flesh and the other only a tip. I know about fungus and have him in a 10 gallon hospital, with every other day water changes and treating him with antibiotic. Any one know what else I can do to help heal him up?? How long do I need to treat him??
