Anyone have T. squamosa? Need placement suggestions

[Delphinus]

See that's where my confusion comes in. Knop is saying "living or dead corals" which to me means "rock" or "hard" subtrate, and to me that suggests that leaving it in the sand is the wrong thing for the clam.

sigh ... I dunno ... stupid clams... would be so much easier if I just awasn't addicted to the idea of having clams in my tanks. I just can't keep 'em happy for some reason ... :(
