Thanks for the replies. Once I get the 2 big ones eating again and looking more healthy I will try adding the little oscar back into the tank. I put the little guy in a 40g since I am medicating the big tank trying to help the 2 big oscars. I saw some white growth on one of the oscars that looks like fungus so I bought fungus and parasite clear medications. I will get some pictures up friday or saturday morning when my girlfriend brings my digital camera back.
