What are some good, non-schooling, colorful, companions for a 4" black veil angelfish I adopted? This angel will so far be sharing a 29 gallon tank with 2, 2" angelicus loaches, 1, 1.5" SAE, and 2 otos (small). I was gonna keep it with all my other loaches until I was given a 30 gallon tank that has more bottom space. The deeper 29 is better for the angel.
