It looks like a white blob, and has a white protruding ex-current siphons at its surface.  One sprung up in the middle of my zoanthid colony, and was beginning to smother them out.   I took a paperclip and poked it a couple times ... is there anyway to get rid of these things?  I know they're beneficial,  but where this one is located just isn't going to work out.
