Unknown LPS Hitchhiker?

[chiefifd]

Hi All.....
I have this LPS (maybe) hitchhiker that I've had in my tank for a few months. I see two or three more in my display tank. There mostly see-thru, very clear even the stalk that's attached to the coral.
Any ideas?
Thanks for checking

Aiptasia, Bad - get it out before it spreads.

Yep defo. Take it out of the aquarium and blitz it with lemon juice or something. Lots of ways to kill it. Search forum. Don’t try to remove it in the tank incase it spreads. I found one on a GSP I bought a few weeks ago, I cut off part of the GSP. No issues since.

Today I addressed my Aiptasia issue.
I took out two small pieces of coral that had one small Aiptasia on each. One other small Aiptasia I cemented in using epoxy. The one larger one that I could reach the stalk I injected it with 1 ML of lemon juice, it shriveled back into its hole. I sealed it in with a good amount of epoxy around the area.
I'll keep an eye out for more that will probably sprout up.
Thanks to everyone that responded quickly.

Good solid approach. Fingers crossed you’ll never see them again.
