Need help

[WilliamTideReefer]

Tank is about two months old and new to the hobby.
Can some help identify these things growing on the rock?

Feather dusters, hydroids, mojano or aiptasia, maybe even small rock nems. Too hard for me to tell from the pic. Someone else might though.

I have had Aptaisa and they did not look like that.

Have to assume you used Live rock from where?
Or you did not quarenteen your coral or other things, and introduced this into your tank.

Lets hope someone can properly identify what it is and determine if its friend or foe.

Also best to take a picture with blues turned off and white lights on
