I don't know what kind of snail it is, but I have small snails all over the place in my tank. A buddy of mine had a 20 gal BW setup that he had introduced snails into for his puffer, but when the puffer went belly up he took the tank apart and I inherrited his bumblee gobies, and aparently the snails as well. As far as clean-up they are so so. My tank is fed shrimp & salmon that I but from the store and freeze until use. What doesnt get eaten the snail swarm over but do not really do a good job of disposing of. Plus they are on the glass everywhere, Ill use an algae scrubber to knock them off but within 24 hrs its back to the way it was. I have heard rumors of some saltwater inverts being compatible but nothing specific.
