what species of Starfish/snail/sand sifter of any sort?

[Rogue951]

Cerith and Nassarius snails are the way to go.
Tonga Nassarius are fast moving dead matter eaters. they only start checking out corals if it's dying or dead. I usually find them on the odd fish body that dies.
but they live in the sand with only their snout sticking out and at the first smell of food (frozen, they don't seem to go after pellets unless they're hungry) they'll come boiling out of the sand.
Ceriths have a tendancy to fall off rocks and get stuck on their backs, then u gotta get in there and flip them
