So our gulper cat (named Puppy) got ich, presumably from feeder goldfish, and we treated it with "API super ich cure" active ingredient 1.3mg Benzaldehyde Green and 1%PVP per 5ml. My SO did the first treatment so I dont know exactly how much he added, but I know he knew he was supposed to do a half dose and I trust him. It's his fish and he's careful. I did the follow-up treatment 48 hours later, per the instructions on the bottle. The dosage is 5ml per 5gal and recommends half-dosing for scaleless fish (like gulper catfish). It's a 75gal tank so I did 37ml. When I did the dose, Puppy was already looking a lot better, though still had some ich spots remaining. The next morning, his whole body looks like its sloughing off its skin... its scaring me. I've never dealt with ich before so I don't know if this is normal or much worse. Does anyone else have experience with treating ich with gulpers or scaleless fish? I don't have any before pictures of Puppy, but this is Puppy now.
