what kind are these?

[luvzz2play]

hello all... new to the hobby and a live rock i picked up started growing these out of the side while a chalice grows out the top and wondered about caring for these. any info would be great as my tank has been up for about 10 weeks now. Oops, just realized that i posted this in the wrong area.... sorry

Hardy corals. If they just popped up they should not take much. Most are easily placed low in the tank but can be acclimated to higher light if done slowly.
