Pest anemone or baby BTA?

[Hondanation09]

Hoping this isn't as bad as I think. I have a healthy RBTA for over a year now in a tank that is 2 1/2 years old. Just noticed this little guy on a piece of rock. S this pest anemone and if so which one? Or could it be baby RTBA.

Thanks

You can nuke them with products like aiptasia-x or joe's juice or simply inject them with boiling water/lemon juice to kill it off. Do not pull or try to remove them, this will cause them to 'shatter' and each piece will become a new anemone inside your tank.
