also how rare are theese guys. (The mushrooms are a bit bigger than the palm of my hand when they are full size)

Looks like R. yuma but you don't usually see them get that big. Could be some other genus/species. I wouldn't say rare but not terribly common either.

Agree, looks like a yuma. Nice corals, but in no way rare, unless it is an unusual color. Hard to tell what yours is in the pic and not knowing your lighting....and hard to tell size from this pic....maybe another pic further away from coral and without a lot of blue light.....
