Need help with unknown life form

[Wheels]

I'm new to salt water aquariums. I have had a 10g aquarium running for about two and a half months. I have to small clowns, a royal gramma, live rock and 5 hermit crabs. Today. this weird translucent/white tenticle thing appeared (see attached picture). Is it some sort of anemone?
Thanks for your help!

It's an Aptaisa, you would advised to get rid of it before it multiplies.

Aptasia are rock anemones that are harmful but there can be a resolution:
Aptasia away or Joe's Juice- Calcium based substance that if swallowed by the mouth should kill them.
Peppermint shrimp or a copper band butter fly fish would enjoy that anemone.
Try to get rid of it before your whole tank becomes a breeding ground.
GOOD LUCK!
