Need An Id

[timpetty]

On a piece of live rock I have a tiny critter but I have no idea what it is. It is about the size of the tip of a ball point pen. It is round bright red with clear/white spines all over it it. Has not moved at all. Unfortunately it is too small for my camera to get a pic of. Any ideas?

sounds possibly like a small bristle worm

Foraminifer?

Foraminifer?

Don't know. The one in my tank is small but easily seen. The only pictures of Foraminifer I can find on google seem to have been taken with an electron microscope
