The fish is new. No, i didn't quarantine. Please, no lectures. I should have....i know. I have a quarantine tank, but it's not set up yet. I tested my h20 and nothing seemed out of the ordinary. I didn't write down the exact numbers, so i don't have them to post. I looked up pictures of Brookynela (sp?), but that's definitely not it. He is not gasping for air. The peeling is from the bottom up. Nothing is wrong with his gills or fins. He is swimming fine. Like I said, the film isn't cloudy. It looks exactly like when you get a sunburn and it starts to peel...all in one piece.
