I have two oscars in my 180. I had a thread going a week or so ago about how I would like to add one or two more fish. Last night a good friend of mine called me and told me a guy he knows has two 10 inch oscars that he is either going to throw in a pond or give them to the neighborhood raccoons. I went ahead and took them but now I have four big oscars in my 180 with a very small pair of convicts. It doesn't look too crowded and I like them all alot. My question is am I overstocked?
