I do see peeling. How long have you had this fish? Can you get to the store tommorow and buy formalin? Look in the Common Treatments FAQ for the correct directions on a formalin bath. It only takes a few days, but you must have a qt tank set up. Brook kills fast, so do not wait! Don't do the directions on the bottle, they are genaric for any disease. Go to the Common Treatments FAQ for info on the dips. If you can't find it, let us know.
