[Dr.Petty]

I got this in a bundle of live rock I got from a friend that's helping me set up my tank does anyone know what it is?

A sponge. They tend to grow out of the light. Harmless filter feeders.

Looks like it could be dead zoa stalks (if that's the right term) that have been covered with coralline algae.
