Hydroid or Aiptasia?

[Picassoclown]

Hey everyone. I posted a few days ago and what I thought might have been aiptasia looks like a hydroid. The main stem comes to a point, it's completely flat against the glass, and is sticking horizontally, as opposed to vertically like aiptasia. Also, my fish seem to be picking at it, where they never picked at aiptasia in the past in other tanks I had. Can someone help me ID this and if I should remove immediately? Sorry for so many pics, tried to get the best details as possible. Thank you in advance.

Hydroid, not an aiptasia

Hello IKD, should it be removed? Will this die off by itself?

You can remove but they tend to disappear on their own over time.

It does not look like aiptasia. There is no mistake on a young aiptasia, They really look like aiptasia except smaller.
