ok.....I completely understand overcrowding situations and even try to not buy fish that will survive in a certain size tank but may be happier in a much more open area to swim..................SO m question is this........as i move into buying corals and mushrooms......do I need to be concerned with over crowding because of the room the corals will be taking up? i.e 5 square inches of coral equal 2 inches of swimming fish????? or something like that?
