Aptasia, an invasive pest anemone.

Can you remove the rock from the tank and cut the chunk of rock with the anemone on it? If not you could try to superglue the mouth of it shut

Superglue? Are they that bad?

 

[Fishmanz]

Pickle juice, line juice, aiptasia x stuff like that or peppermint shrimp , copperband butterfly

 

[sfin52]

Yes they are that

You you can remove the rock, get a lighter or small torch and burn it off. No joke, they can take over your whole tank.
