Please Help me identify this Coral

[Tripod1404]

Hey guys, since we have this subforum, I decided to post my question here.

I got this coral from my petco for 4$. I usually dont buy livestock from petco but this particular store actually has a good track record. I was observing this coral at petco tank for a month and it looked fine and actuality grew a bit. Unfortunately they couldn't identified its species and I couldn't either. It kinda looks like a flower pot coral but coloring doesn't exactly match. Do you guys have any idea what it might be? I attached some pictures of it

5 days ago I placed it to a medium flow/lighting area and it seems to like it there. As soon as the light turns on it fully extends its polyps and even during the night it doesn't completely retract them in (crown of polyps remain outside).

At a glance it looks like a green gonipora to me. Is there a hard skeleton on the underside? Mess with the coral and see if it retracts into a hard skeleton. If it is, you got a steal friend.

Yes it does. It was hiding in the hard skeleton when first put it in the tank but quickly opened up in about 10mins. Actually I didn't even acclimated it and directly put it to the tank. Since it was just 4$, i tough it is something hardy. If I knew it is a goniopora I would probably be nervous as hell . Well I should begin target feeding it then

Yes, totally a goniopora.
