Can someone ID this?

So I bought my first 2 pieces of coral for my 125 this weekend. I bought coralRX and followed instructions. Now the coralRX did get everything off the coral, but didnt kill anything. I found a bristleworm, some kind of star, a few white bugs, and a big brown one. Nothing was dead, but thu did fall off.

Anyway, my question is when I looked at the mushroom rock I bought, I found these little guys on one side of it and I'm not sure what it is. Initially I thought it was aptasia, but the extensions have these little extensions coming off of them. Below is a picture, can anyone ID them?

It looks like Anthelia sp.. If conditions in your tank are at all good they should grow well, some people actually have too much because of this. Keep an eye on them as they may spread fast.

Yeah I've herd they could be a few things, but nothing bass...I just need to watch it like you said. Thanks for the reply!
