Unknown on Live Rock

[mlipst]

The attached picture shows a hard slow growing branching growth that came with my live rock. Can Anyone identify it?

I don't believe it is a coral. I think it is actually a marine algae called Codium.

Definently some type of macro algae, can't give you the specific name because i don't know. Thats cool it came on LR though....LR must be good stuff, very alive.

Is that a Zoa/Pally polyp or a small anemone in the top right. Just above the macro algae? Or a mushroom perhaps!?!

Looks like some kind of macro algae. I'm not sure what kind though.

The thing above it looks kind of like a ricordia to me.

i dont see any ricordea lol maybe majano but defintly some type of macro algae....most tangs will eat that stuff (not saying to run out and put a tang in your 20g)

Could be majano. I have some rics that look almost exactly like that (as far as I can tell from the pic) - and they are definitely rics.

yea hard to tell from the pic...ive got some yumas that look like that too

Thanks for all your responses. Based on evaluation of further web references and pictures for the species names provided, the green mass is Codium and the item on the above right (which also came in on live rock) is Ricordia. I've actually had both for about five years, but recently upgraded from a 38 gallon tank to a 75 gallon with better lighting. Things are taking off now. New live rock added to the tank came with a 3 inch Sea Hare and a 3/4 inch Sea Hare, and a whole host of small feather dusters.

That is some high quality live rock. Where did you get it?

The rock was purchased from a local pet store, Pets Plus, in Lawrenceville, NJ.
