#1. Green Star Polyps with what looks like zoas growing out of it. (maybe algae, but looks like zoas)
#2. Toadstool Leather with some macro algae attached to the rock.
#3. Digi coral laying on the sand with some macro around it. (Move that digi..get it off the sand and get it at least 1/2 way up the tank..it'll turn brown and die where it's at)
#4. Mermaid Fan
