Olive Periscoping Snails

[HeulittSalmi]

A guy at the LFS recommended these as sandsifting Snails that would work and make my sand nice and clean is this so?

Olive snails are predatory. They will consume your snails and bivalves. Nassarius snails are much better at consuming detritus and any uneaten food that may fall to the substrate.

What about sandsifters that eat Algae?

 

[K. Steven]

Algae doesn't usually grow on the sand. Turbo, cerith, and nerite snails will eat algae, but mostly on the rocks and glass.
