HI everyone!! I'm so new at this, I haven't even bought a tank yet!! I've been reading this site to see what I'm getting myself into before I take the plunge. I'm going to start with a 55 gallon tank and I guess the biggest challange I have is deciding whether or not to get a bunch of little fish, or a few big fish. From all the posts that I've read so far, the Oscars seem like great fish to have, but I don't see myself ever owning a tank bigger than 55gal. I'm considering one Oscar, one pleco, one or two Jack Dempsys, and a few little Cory Cats (to help clean the bottom of course). I know the Oscar and the Pleco will get pretty big so will that leave enough room for the others that I've mentioned? I'd appreciate your thoughts and comments.
