Well...rather than say "I don't know"...again
, I did a little digging. I do not believe it is ricordea, I think it is Discisoma (=Actinodiscus) sp. I can't find a link with a bunch of pics, but that is what I think. Unless someone has one of these and has done the reasearch, I think it is doubtful that you will be able to ID it further than the genus. I did find a description of a particular ricordea that I found could
fit the bill...Ricordea cf

Both are very popular in the aquarium trade. Ricordea yuma is readily distinguished from R. florida by the fact that the former has pseudotentacles on the oral cone, while the latter does not. Also, R. florida often has numerous mouths and elongated irregular polyps, while R. yuma is usually circular, with one mouth. All are spectacular due to the grape-like tentacles on their oral disc, but some especially prized specimens have brilliant fluorescent proteins in shades of orange, red, pink, blue, and green.
