Aiptasia or paly or something else?

This has been slowly growing on a zoa frag over a few months and looks like aiptasia to me. Out of interest I asked ChatGPT (same image) for id and it said it’s a paly (Protopalythoa) with the logic that it doesn’t have a stem and greater number of tentacles.

I’m assuming ChatGPT is wrong. Just want to check! Thank you.

Could be a majano. They are similar.

It's a pest anemone, majano or aipitasia. Since it's isolated, remove piece and treat.
