I have never really liked Oscars. I thought they weren't that nice lookin and it seemed every tom, dick, and harry had one. Until last week when I went into my lfs and saw this guy sulking in one of their tiny holding tanks. He was looking very thin and neglected. Well I'm a sucker for a fish in need so one look and I had to take him home. Plus, my lfs let me have him for 10 bucks!
The previous owner fed him mostly goldfish and kept him in a 55 gal aquarium. How he made it to 13+ inches I'll never know. Anyway he has a bad case of hith. There are 3 holes. 2 are the size of pin heads and one large one behind his left eye. His nostrils are also looking kind of damaged. I haven't really looked at an oscar up close, so I don't know if they are normal or not. I have done research on it and switched him over too pellets (only took 3 days) and water params are good (0 amm,0 nitrite, 20ppm nitrate,7.4ph). I read the thread about hith and wanted to know if anyone has healed it on an oscar? I was also wondering if 20 ppm nitrates is low enough to help heal the holes? If anyone who has dealt with this could give me some advice, I would appreciate it. Here are some pics for reference.
