Snails in aquarium, good or bad?

Whether we want them in the aquarium or not. We all can admit that snails are good cleaners in the fish tank.

Moreover, they are scavengers feeding on algae and ensuring to a degree that the water is clean. Having a small quantity of them is generally not a bad thing.
