I need help identifying what is in the picture

[Geloky]

I used dry rock and sand. The only live thing I put in tank are fish and cheato from Algeabarn. I saw this thing in the rocks.

Aiptasia. Probably came in with the cheato

 

[AcroNem]

I 2nd Aiptasia.

Looks possibly like a Mejano or aptasia anemone to me. If you can take out the rock and kill it outside the tank that would probably be best, or you risk it spreading... an annoying pest. A tiny remnant could have snuck in on the Chaeto. You might want to look around for others forming in the tank.

Yep, it’s aiptasia.

 

[SaltyCupcake]

+1 Aiptasia. May have come in with the chaeto, sadly. I read in this forum recently that someone's 'clean chaeto' came in with one of those things. Sorry

Aiptasia super glue that bad boy into a tiny, evil little coffin

 

[Casket_Case]

It’s Aiptasia. Use a very small amount of lemon juice in a syringe, boiling water in a syringe, or you can buy Aiptasia-X from Red Sea.

Thanks for quick responses, I will remove the rock Good thing I don’t have corals yet.

 

[GeoSquid]

I put concentrated Kalk then dried it in the sun.
