Thanks, we want to add more color with some corals. Any suggestions? Thank you everyone who gave us advice on the clowns, we decided not to add anymore, we'd like a copperbanded but, not sure how the Tangs will accept it. also, somewhere hiding in the tank is a Pom Pom crab haven't seen him since the move and my mandarine came out for a second the other day.
