I have a 37 gallon aquarium that has been up and running for a while now, so I'd like to turn my attention to setting up a planted (low light plants) 10 gallon bio-wheel aquarium that I've been neglecting. What would you suggest for interesting fish for a tank that size, other than the usual neon tetras? I've been putting off setting up the tank because I don't know of any cool fish that will thrive in a small tank. Thanks.
