Chromis, 6 line, royal gramma. All fairly common. I have all of these, plus 2 Clarkii clowns, a tail spot blenny, lawnmower blenny in my 58 and I have plenty of activity. I had an Eibli angel, a great looking fish, but he took a liking to my Trachyphyilla brain so he left.
When I get around to setting up my 75 I hope to add a few more. I'd like a tang, maybe a yellow or scopas, and a Genicanthus sp angel.
