I just bought a maroon clown last Saturday and brought him home. He has a torn fin on the bottom and top. I put some Melafix in the qt for 3 days, then I noticed he's got white patches on him under his lip and around his gills. I also noticed his poop is white. Are these worms? Kind of looks like something is burrowed under his skin on his face around his gill. I put coppersafe in but is this the right treatment? Please help as I really like him and haven't had much luck when it come's to clown's.
