Has anyone seen a listing that shows where different types of fish generally prefer to be in the tank in terms of depth? I guess I am kind of looking for a fish breed that likes to be near the mid to upper levels of the tank. I have corys, a pleco and pictus cats right now and they all tend to work the bottom most of the time. Id kind of like something I can actually see in the tank once in a while and isn’t hidden in my drift wood or plants all day!
