You don't need to use anything other than lettuce. Float a lettuce leaf in the aquarium overnight, and in the morning it will be covered with snails. Then, take it out and throw it away. Do this until there are no more snails.
Some snails have very interestingly designed shells and can add color and uniqueness to an aquarium. Also, snails are an algae consumer and help clean the aquarium. Some fish also require snails as part of their diet, such as some puffers.

Aquarium snails are different from regular land snails. All aquatic snails have gills. Just like their land relatives, these snails also have radula(rasping tongue),tentacles, and hard shells. Aquatic snails do not have as developed eyes as land snails. Many aquatic snails have a door or an opcerium at the entrance of their shell. Some aquatic snails also grow to the size of a baseball.

Snails are hermanphrodites but they will not self-fertilize. Only plants do that.
all snails have both male and female parts
A low pH can cause the calcium carbonate shells of snails to deteriorate, and eventually kill the snails. A pH of 7.0+ is best.
