Zoa Help

[Abot559]

Hey guys I recently started adding corals to may tank and I got my first zoa recently. The other day I noticed these tentacles come out when my light turns off. Is this normal? I tried doing some research but couldn’t find much.

Those aren't Zoas, those are Favias or Favites from the looks of it so they're a Large Polyps Stony coral (LPS). Feeding tentacles are perfectly normal for LPS and are a good sign. I love Favias/Favites! Not sure on specifics but yours looks like maybe a War Coral. Either way, they can send out sweeper tentacles as well to attack neighboring corals so give them an inch or 2 between them and other corals so they don't sting each other.

Be careful with favia/favities/moon coral/war corals they can have very long sweepers and pack a punch.
