I currently have a 48x24x18in tank that does not have substrate yet(I'm willing do bare-bottom if I need to)and I have no clue what to stock it with. I am leaning toward cichlids but I also want something unique in one way or another. I can't decide whether to do a biotope, a community, or a cichlid tank. Also, I don't want to have to grow out or upgrade my tank for any fish.
