I'm looking for suggestions for an encrusting coral to put on the back wall of my biocube 29. It'll probably be my last coral addition to the tank so I want it to be real special. I thought a meteor shower would be cool but I want something that will spread and my cyphestrea I already have seem to hate light. I'm running 165 watt LEDs and an open to every kind of coral, (well... no star polyps). Let's see some real nice suggestions from you guys!
