I had this Red Oscar for about months and is about 6 to 7 inch. I keep him in his own 20 gallon long tank. The tank has no plants just rocks. The problem I am having is that about 3 days ago he started not to eat. The next day the oscar rectal area was enlarged and had a cotton like substance coming out. At first I thought that he had swallowed a rock and was just trying to pass it. But know the white cotton (fungus) is on its right fin. A small dot. I treated the tank with fungus cure and coppersafe medication today. My question is, has anyone had this problem and how did you treat it? I hope I don't lose the Oscar due to this. Was planning on putting him in a 250 with couple of clownknifes, pacus and a royal pleco.
