I purchased a young wild caught Oscar about a month ago and have been growing him in my community tank. He is now at the size where he is ready to move into the 125 I have for him but every time I move him he just sinks to the bottom and his scales start turning white and falling off. So I put him back in the community tank and he's fine.
I do not understand what's wrong. I have south american cichlids and bichirs in the 125 and they have never showed any problems and are growing and eating great. I clean both tanks weekly doing a 33-45% water change. Both tanks are controlled by a JBJ thermostat and are identical temps, lighting is dimmer in the 125. None of the other fish pick on him ever. I really need to move him but I do not understand what is going on.
