Acan ID’s?

[TnFishwater98]

I know the one in the back is a Acan and the one in the 2nd pic. questions :
Is the coral closest a Acan also? Favia?
Can you tell if they are Acans if they would be good neighbors? (Same species)
Tanks!

Looks to be a Favia. Be cautious if it is a Favia, I have seen them have exceptionally long sweeper tentacles.

Certain types of Favias or most Favias you think have long Sweeps?

Can't say for certain about all but all the ones I have ever owned have, indeed, shockingly long sweepers. Makes you wonder where they hide them. A fine example of that can be seen here...

That is definitely longer than what I thought. In my mind I was thinking a Chalice or hammer might extended that long.
Do you know if most Favias get along with other Favias or does it depend on each species?
