So I searched and only saw one thread about oscars and hole in the head and it was locked so...
I have an Oscar
in a 75. A few years ago he started getting hole in the head, I did some research, decided I was letting the water quality get out of hand, and upped the changes and it went completely away. I have a 125 waiting for a stand and figured I'd put the Oscar
in it and get a few more larger fish. Well, a friend has an Oscar
in a 12 gallon tank (I know, I'm not sure what he was thinking) and he's not taking proper care of the tank. He wants to give me the Oscar
for them to share the 125. I want to take it, but it's got hole in the head.
So, I know 125 is big enough for 2, it'll be a new set up for both so I don't anticipate territorial issues, and I'd like to give this poor bastard a decent home, but my biggest question is, is hole in the head contagious? Can I fix him with good water quality and good food, or will he infect mine and maybe they'll both die?
