🐌 What Are Freshwater Snails?

Freshwater snails are aquatic invertebrates that live in lakes, rivers, ponds, and home aquariums. In the aquarium hobby, they’re often used as cleanup crew because they help keep the tank clean by eating algae, uneaten food, and detritus. Many also add visual appeal with their unique shell colors and shapes.
