Keep it or nuke it.

The 2nd picture is at the back of the tank. Growing at a 90 degree angle of a lower rock.

The 1st with the arrow is another growth, this one is growing on the rock. Picture from the top

Any ideas? Evasive and take over my tank?
Foraminiferans?

Thank you!

That last photo is Aiptasia for sure.

Make 'em go away, if you can.

Aiptasia! Thanks folks! I’ll see if it’s on one of the smaller rocks that I can remove from the tank.
