I just go a 55 gallon tank as an early Christmas present and I cant decide what to put in it. I had originally settled on 2 polypterus senegalus and a couple of opaline gourami but then I found out I could keep an oscar in it. I like the oscar idea as they are more active, predatory, and can be taught tricks, but I dont like the idea of them redecorating my tank and being the only fish in a 4ft tank. Some one please help me decide or give me more ideas on what to put in my new tank.
