I agree with puffer. I recently added a Coral Beauty to my tank...brilliant blue/violet (can;t see the violet, I'm colorblind...my wife had to tell me) with golds. I had 2 GSM's and 2 Pajama Carinals in there to begin with. I had heard that angels could be a bit aggresive...not the case with this Coral Beauty. It's fit right in...in fact, it seems to hang out with my larger GSM. Also...it hasn't messed with any of my inverts...a few little nibbles have taken place, but no damage.
