Duncanopsammia is the one on the bottom right, and the one on top is a red/green open brain. I have another red open brain in the back corner, on the sand where they do best. One can risk tearing the brain on rock or other staging areas, I was very careful on my placement ha. Those are pink colt corals…beautiful display pieces to any reef. They grab the attention most in my opinion. My favorite is my darth maul polyps.
