If you are planning on keeping angels, I would be careful about which fish to add with them. There are a lot of fish, but just try to stay away from the 'known' nippers. Rainbow fish do very nicely with them and they do not bother each other, plus the rainbows grow nice and large for your tank. Any of the catfish would do ok as well. A pleco, cory cats, rasbora's as well. Angels like to stay pretty much at the top half of the tank, so any bottom dwellers would work. Tigar barbs can get nasty and some tetras as well, like the serpae tetras. You can try German blue rams, or bolivian rams too. I only have Discus, rainbows, cardinal tetras and two bolivian rams with mine at the moment. Im sure there are a host of other fish you can add as well, and hopefully others will come along with suggestions for you.
Good luck with your tank!
