Hey, I'm new to the reef scene and was wondering what is stuck under my zoa frag plug. I've attached some pictures. They look like a polyp of some sort but I'm not exactly sure. TIA

Looks like an anemone.
possibly aptasia ( not spelled right I’m afraid)

Good morning AAkuu and welcome to TRT! I agree with Jerry.......from what I can see in your pictures it does appear to indeed be aiptasia. ("I had to look up the spelling myself Jerry because I couldn't figure out why you thought you were wrong......very close.")

I would put it in a separate container and scrub, or scrape it off......it is seriously invasive if left unchecked.
All the best,
Hack
