Green Polyps or Some Type of Anemones?

[Benjamin J. Young]

I bought a small rock with Coraline on it from my LFS to seed my nano. It's been a few weeks, but I just noticed this finding shown in the attached closeup image. Appears to be neon green little things. I think they look like the Aiptasia I just killed that came with some of my frags. However, these seem to be pretty, are very tiny, and in a cluster of eight. That whole cluster is about the size of a half of a pea. Not sure what they are, but maybe someone else does?

Not the best at ID's, but kind of looks like hydroids to me. Please wait for others to respond to confirm or debunk my guess. @KJ

Do they have a soft tube skeleton? I'm going with colonial hydroids as well - remove ASAP.

Definitely does not look like GSP, I agree with what the others said as well, looks like colonial hydroids. This pic is from another thread on here.
