Can I get an ID please

See pics. This is growing out of a piece of gulf live rock that has been in the tank about six months. It’s not obviously multiplying and does not look like any Apstasia I have ever seen.

It might be hard to see in the pics, but some of the arms have horizontal banding and most have bubbles ending in small curled tips.

I’m just checking in case it’s something potentially invasive. My norm is to encourage diversity where possible....

Aptasia 100%. You'd better kill it ASAP.

Kalkwasser paste works great, hot water or lemon juice may help also.

Thanks. It’s been years since I’ve had one, and they looked much different. Flatter oral disc and long stringy tentacles. This one looks more like a BTA mounted on a stalk. Will dig out the kalk....
