I have a Regal tang with white growth in front of his eye. I bought him three weeks ago and he is in quarantine. He developed this white growth in front of his right eye. At first I thought it might be ich so I dropped the salinity down to 1.09. I don't think it is ich as the growth has gotten bigger and there are no other spots on the rest of him. Any help identifying this condition and curing it would be greatly appreciated. He is a very cute fish and I would hate to loose him. He seems to be eating OK.
