Is this Aptasia?

[Yates273]

Hello I’m new to salt water and through this site I am learning everyday. I just spotted this on my live rock. Is this aptasia and if so should I let it grow a little more before I eliminate it. Was thinking about the lemon juice approach. Thanks

Not aptasia... Hard to identify exactly because it is blurry but it is definitely not an aptasia..

Not apt, hydroid possibly, hard to tell from pic but look those up and see if that is what you are seeing.

One thing I should add is when I tap on the glass it retracts immediately

hmm, maybe just a feather duster, but again hard to tell from pic

Look up hitch hikers on lionslair or melevs reef maybe
