R.S. What size tank and how many angels are you planning on?
With the angels I have and have had I've kept glo light tetras, zebra danios, gold long finned danios, cory julii, and pekolita sp clown plecos. But be warned, the best fish in my experience with angels are smaller fish that can move faster than the angels. Not all angels will be nippy, but they have been known to get a bit aggressive, to say nothing of chasing the other fish off the food.
