Well i am thinking african flameback with my potters... the flame back wont grow near as big so i am hoping that the potters establishes domanance fast.. they will be added at the same time..same bucket for acclimatizing..

Have a Coral Beauty, and a dark blue pygmy angelfish, can't remember the proper name, and a Majestic Angel, They were all in a 72g but are in a 90g and soon to be in a 140g, chased each other now and then but lots of rock in tank..no problems. I believe rock is the big factor in keeping them from beating the crap out of each other.
