Haven't seen any as of yet, but I don't recall seeing them right away in my other attempts, either, and yet they were there when I broke the tanks down. So I'm assuming they are there.
You can see the clam thing in the picture with the red macroalgae on it. It's tall and upright in orientation.
So far as the other corals-- I haven't the foggiest idea what they are. We are going to start with some zooanthids and xenia. I eventually would like to get some LPS... frogspawn and hammer coral in particular!
