Acan ID Help

[crabgrass]

I added a few coral to my tank today. The one of the right is an Acan (Lord?). The one on the left was a Freebie - I just wanted to confirm this was indeed an acan (Lord) also.

Thanks!

1st one is a Dipsastraea; 2nd one I'm not sure. Might be a true Acanthastrea (commonly referred to as echinata by the hobby)

Thanks. If that is the case one of them needs to move, right?

Yeah; both Dipsastraea and (true) Acanthastrea are pretty aggressive, Dipsastraea by sweeper tentacles and Acanthastrea by mesenterial filaments.

They have been relocated. Thanks!
