Is it Aiptasia or something else?

[MarineHobbyist]

I recently got a colony of Zoanthid and I have been observing it in my Quarantine for weeks and I noticed hair like white thing on it and soon it multiplied.
Wondering if it is Aiptasia! or something else. Please help me figure out.

Looks like hydroids, but @KJ to be sure.

Manual removal, reduced feeding, discontinue any broadcast feeding and feeding of any liquid foods. They should subside lacking a food source.
