Aiptasia ?

Aiptasia? Other? Retracted pretty quick when I went after it with a pair of tweezers

It looks like Aiptasia.

I like to use Aiptasia X for random ones like that.

Was gonna do this or just some superglue in the hole it’s tucked into. Haven’t noticed any others so fingers crossed it’s a stray and not the start of a plague

As long as you keep an eye on the tank, and take care of them as soon as you see them, you should be okay. They will come in on random frags that you add to the tank.

If there is one then there is probably more. Please know that isn't horrible and can be dealt with. IMO, if you start with F-Aiptasia, Aiptasia-X, or one of the other standard remedies to treat the ones that you see and then if they start to get out of hand and you can't keep up then you can add berghia nudibranchs. Good luck with whatever you choose!
