I like the shorter and deeper tanks, they make for much more depth in your tank. But It will be fun trying to find lights that will properly light your tank. But If your not going to go with Coral. I really like puffers, such as the dog face, an Angel, a H Tusk, I'm really wanting an eel right now for mine. I'm really wanting a pair of cinimon clowns too. they'll get pretty big, and quite beautiful.
