favia or acan?

favia.

how can you tell the difference. It is hard for me to tell.

favia

Regardless of what it is, its Beau-ti-ful.

agreed

one easy give away is the fact that the polyps are all interconnected. acan lord have distinct separate polyps. acan echinata, subechinata, and hillae have interconnected polyps tho, but they look very different than favia, so easy to discern.

Favia for sure, but a very nice one too.

Agreed on favia, too. Like Tigahboy said, the polyps "gel" together on favia more-so than others. Great looking piece, though.

i like the bright green centers

kinda like alien eyes looking at ya !

favia and i have a piece that looks very similar to that. check out my gallery at rc.com to see the pics. nice pick up!

thanks for the help and nice comments.
