Hitchhiker polyp on a frag mount ID

[terahz]

I got this frag about a week ago and just noticed these two tiiiiny little polyps growing on the side. They are probably 1-2mm big wide and are grey with greenish color on them. Not sure if they are still baby zoas that formed from a leftover tissue by the original holder of the frag or something that decided to show up now. What do you guys think?

It looks like it may be a new polyp of the ones above it. Sometimes they drop off, start small, look off color for awhile, and then grow into beauties.

more than likely a baby of the current polyps on the frag
