Nice fish, Pete.
A quick question for you: was the wrasse picking at the zoanthids, or picking around the zoanthids?
I have two yellow coris wrasses that hunt for 'pods and other small inverts all day long. They circle my zoanthids and my small toadstool, and dart in between to snatch a bit of food. Sometimes it looks like they're picking on the zoos, but I think they're just nailing some 'pods.
