Arthur,

Platypodiella spectabilis http://www.reeflex.net/tiere/2498_Pl...pectabilis.htm is a Xanthid crab and omnivore. It is said it feeds sometimes on anemones.

There is nothing more known about this crab – although with the scientific name You can search at least. How big is it (only carapace width)? It surely may live some three to four years but this really is just a wild guess because most crabs at least can get that old.
