Acan or Favia?

[Dsnakes]

I am new to R2R, and fairly new to saltwater. I picked this up at my LFS and it was listed as Acan. Is this indeed two types of Acan? Or Acan and Favia. Specific types? Should I frag them apart? Thanks for the help!

Could this be Acan Hillae and Lord? I know they were recently reclassified, however these two seem to be the closest ideas I have found.

So I know the red part is lord. Can anyone tell me for sure if the other half is Hillae? I have fragged this piece into 4 pieces, 2 of each kind. All are filling out well
