Is this an Acan?

[GraniteReefer]

So one of my favorite NH LFS (Plymouth pet and aquarium) is no longer going to sell saltwater livestock. I wanted to get one last coral from them and they only had 5 little frags remaining by the time I got there, so I bought what I thought was an ugly Acan lord(I know they are reclassified). Now I’m not sure if it’s an Acan echinata. Or something entirely different. Help me decide so I can know if I can throw it next to other Acan lords safely. Thanks!

I’m surprised on the news of them stopping the saltwater side of things. They have had saltwater fish and corals for some time. I loved stopping in there. Bummer

Looks like the favites sp. I have in my tank.

Maybe an echinata or favia. Sorry, don’t know a lot about the differences between favia favites and echinata, but it looks more like either one of these three.

Not related, but I see that captive bred mandarin in the top right! What a cutie, check out my new thread on mandarin photos and post yours too! Here’s a shot of mine: Anak.
