Think you mean Nassarius snails?
Sand dollars work, I have one, and although it's pretty, don't expect to ever see it. Every once in a while I'll see a lump of sand moving so I know it's still around, but it never comes uncovered - never.
Also hedgehog urchins (I think that's what they're called?) Albert had brought some into Golds back in January-ish. Burrows in the sand.
Tiger tail cuke ...
... and conches.
