I have seen these little guys at just about every beach I have been to. If you kick back the sand where the water is breaking there are little clam looking things that push themselves back under the sand. Would they serve any benefit in a refugium or a remote dsb?

Donax variabilis

If you,swim out to chest deep and grab some sand, take it to shore and in the shells you will find hermit crabs

Donax variabilis

or Coquina Clams. I have a dozen or so in my tank. Not sure if they help but they look cool.

how long have you had them? and do they actually surface and move or do you just see them when the sand is disturbed?

They do move around and walk over the surface. The guys in the refugium are original (6+ months). The guys in the DT tend to get eating by other things in the tank.

I think a lot would depend on what you've got planned for the tank. They'd probably do alright in a more nutrient rich tank. I think they would probably just starve and die in a low nutrient tank.

I could have sworn I've heard of people going to the market and buying clams and sticking them in their fuge...

If so, is this smart?

Well I know you can get a recipe for coquina clam soup online :)
There are a number of online stores that sell clams of various sizes, but since I can get them for feed at the beach... Well, they are a cool addition to the tanks.
