New tank; aiptasia?

[Res_Ipsa]

I'm 3.5 months into my first tank and saw something growing on a frag plug that just appeared overnight. It's very tiny but I tried to get the best picture I could. Not sure if it is aiptasia or possibly something else. I entombed it in a drop of superglue last night in an abundance of caution and haven't seen any more in my tank.

Is this a baby aiptasia?

Looks like a majano.

I was gonna say majano too.. they’re a nuisance like aptasia.
