Red Hitchikers on new zoa colony

[Euphyllia97]

Hi guys!

Bought a small rock with zoa’s today and wanted to check for any nudibranches or eggs by night. Came across these red hitchikers, but have no clue what it is or whether it is reef safe or not.

Picture by night so sorry for quality

I can't ID them, but they look like baby anemones or zoas. I'd keep it in a holding tank for as long as needed to see what happens. You know the old saying... "If in doubt, get it out!"
