I recently got a Bi color Angel for $25. Almost 3". I did minimal reading before and have since seen that people say its not an easy dwarf angel to keep. That it is not a hardy fish. Would like to hear fron others about this. I actually bought an Bi color and a Flame Angel together. They were kept together. The Flame seems more timid than the bi color. I put them in what the heck my Coral Beauty. They was some initial aggression but so far they are leaving each other alone..
