Acan or favia?

[cpate]

Picked this frag up from a guy that was breaking down his tank and he said it was an acan but I’m not so sure.. what do you guys think?

Tough one but I’m going acan echinata.

Agreed, looks like acan echinata to me. Favias have more distinct heads, acan echinata are less distinct, kind of look like a mix between acans, favia, and chalice in my opinion.

I agree, its acanthastrea echinata
