Here's the story... imstarting my first ever reef tank, and just bought a bunch of LS and LR from a guy and took 30 gallons of his SW to get the tank started. After putting all the sand and rock in I noticed these things on the rocks, and was wondering if anyone can ID them, and if so, should I be feeding these guys even though Im not done putting LR into the tank ?? The last three pics are of the same thing, just a TON of that stuff one the same piece of rock, and the second one I just didnt know what the neon green stuff was....

I also got a TON of little blue legged hermit crabs and a bunch of snails.... Nice that I hopefully wont have to buy any now...

First shot looks like a type of Palythoa.

The others look to be a type of Rhodactis.

The yellow is probably a sponge or tunicate as stated.
