As everyone knows Oscars think that they're interior decoraters and will move everything around the tank. Because of this I have 4 rounded rocks and one plant in my tank because anything else, my oscar will just tear up. I decided to put on a background because the tank was looking rather bland and when I did, my Oscar layed on the bottom of the tank all day. I was curious if it could possibly be the background, so I took it down and 5 minutes later he was up and swimming as to normal and has been ever since. You think the background had anything to do with it?
