I don't have any pictures of the small clams from Indo-Pacific, but they are black in color and they are about the size of a penny. I don't stock them per recommendation because I use other stuff as well, such as numerous brittle sea stars, serpent stars, sea cumcumbers, lots of sponges (came with the liverock from Tampa Bay Saltwater) and large mollusks/jewel box clams (also came with the liverock) as well.
