The Leopard Nerite Snail is an extremely docile creature and does not bother any other inhabitants. They clean algae off of glass, plants, and decorations, they eat hair algae, and they keep your substrate clean and the correct color.
Nerite Snails are widely believed to be the single best snail in the aquarium hobby for eating algae. They are totally safe with any fish, shrimp, or plants, and are completely peaceful. Nerite Snails require salt water to reproduce, so they will never overpopulate your aquarium (as some freshwater snails are known to do). They are also peaceful and safe with live plants, fish, and shrimp, making them great for community tanks.
The Leopard nerite snails are best kept in a covered tank as they tend to venture above the waterline. An interesting observation of these nerites is that their tentacles stay straight even when out of water.
These Nerite Snails reach around 3cm. They do not eat plants (only algae), so they are perfectly suitable for planted tanks.
