Notes: There are several species of Nerite Snails available in the trade, from freshwater to brackish to fully marine. The commonly sold Clithon Nerites are freshwater snails that will readily adapt to half strength seawater. They are often purchased to consume algae and they target several types of brown and green algae. As they come from well oxygenated waters, they do best in tanks with robust filtration and water movement. These snails are known for escaping tanks and can survive out of water for long periods of time. If found out of the tank, they should be returned and will likely recover fine.
Clithon Snails will lay white eggs on tank decorations and plants in the home aquaria, but these will not develop in freshwater. Depending on the species, the larval stage of these snails require high end brackish or fully marine conditions in order to develop. Attempting to raise young snails would require a separate aquarium as adult snails can not tolerate these conditions.
