I know of ONE local retailer that is advertising them as
"A striking addition to your invertebrate clean up crew.
These snails are small (1/2") detritus eaters. Although they will climb on your rock and aquarium glass, they prefer to stay in the sand bed and scavenge for left over waste that was missed by other custodian members.
We recommend adding approximately 1-2 Bumble Bee Snails for every 2 gallons of aquarium volume. "
That's being recommended as part of a reef clean up crew.
