I am fairly certain it is Diodogorgia nodulifera. The callous-like spots where the polyps extend from within are rather distinct. They hail from Caribbean waters over 50ft. deep. These gorgonians lack the zooanthellae (symbiotic algae) required to photosythesize, which is why they must be fed in order to thrive. You could probably get by with phytoplankton, but perhaps better off with more planktonic food such as rotifers, eggs, and copepods. Remember with lfs
salesmen, they are there to make a sale and often don't know much about what they are selling in the first place.
