Well my tank is almost complete. I just need a few middle-top area fish. I need fish that are min. 3" and max 6" long. They can be tall. I want one that is active. I have nocturnal bottom dwelling fish and a couple surface dwelling fish but nothing in the middle so the tank looks empty when I look at it. I want peaceful fish but semi-aggressive will be ok. I figured a pair or three max. as I am nearing my max amount of fish to have in this tank. I like to look at colorful and/or graceful fish. I can't stand fish like certain tetras that will dart around the tank. I was thinking angels but I've not seen any I liked at the store. They just kinda look.. plain.. as far as color goes (the only store I trust to buy fish from only have black and white striped ones). Any ideas as to what other fish there are that would fit these parameters?
