Unknown Coral

[Briol]

Hey everyone!

I bought this coral as one small polyp that looked like a blip of yellow on some flesh. I grabbed it from a random $5 bin and the guy at the LPS wasn't sure what it was. It has grown to about the seven heads you see in the pic. (It had two more but I had a small die back last month.) I really have no idea what it is. It doesn't seem thick enough to be a chalice, its not an sps that I know, could it be a type of zoa? But the polyps aren't really separated enough for that... I'd love some feedback and have attached a photo below. If you want me to try to get a different photo, let me know!

Looks like some type of cyphastrea

Small goni or zoas? Pic is kinda far out and dark. I'd take care of that aiptasia in the sand quick!

And a big aiptasia in the sand

Cyphastrea makes sense! Thank you! I killed the apitasia -- sorry about that! I keep a needle and lemon juice by the tank. In a few months I'm hoping to get a copper band butterfly to help with controlling them. I'm glad the coral is in a good spot. It seems happy there. I'll have to research it a bit more (I haven't had one before).
