No, they suck off algae in the tank.
In the aquarium were water, weed, sunfish, snails, and a neon fish.

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.
A denizen is an inhabitant of a particular place, so anything that lives in an aquarium is a denizen of an aquarium. This includes fish, plant life, aquatic frogs or snails, etc.
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.
They can just live in an aquarium with the normal pebbles on the bottom that all fish live in.
