It grazes on biofilm and many soft algae coatings on glass and décor. It does not replace normal maintenance and needs supplementary food if natural grazing is scarce.

Nerite-type snails may lay eggs in freshwater, but their larvae normally require brackish or salt water. A growing population is therefore unlikely in freshwater.

Stable mineral content and dietary calcium help maintain a strong, healthy shell. Avoid very acidic, mineral-poor water.

Yes, snails may climb above the waterline. Use a lid and check water quality if a snail repeatedly tries to leave.
