Horned Nerita Snail (Clithon sp.)

Horned Snails Clithon sp also known as Crown Nerita Snails, are popular options for aquarists. They provide a beneficial addition to a freshwater aquarium or pond due to their algae eating ability, especially enjoying Diatoms and Green Algae (as well as Cyanobacteria to a lesser extent). They also keep uneaten food and detritus in check. No two look exactly alike, but they display yellow oblong shaped shells with thick black whorls and protruding spines in a configuration resembling horns or a crown. Individual snails within the same population can contain a variety of spire heights, color differences, and patterns.

Nocturnal invertebrates, they are sensitive to ammonia spikes, copper, and copper compounds. Peaceful snails, they will not unexpectedly overpopulate your aquarium or water garden since they do not reproduce in freshwater. They are hardy and grow to 1” in length. A lidded aquarium is recommended to keep these little snails from escaping. Because they like to burrow, sandy substrates are the best choice for this snail.

Although they are scavengers, it is important to supplement their diet with algae wafters or blanched vegetables like carrots, sprouts, spinach, cucumber, and zucchini.
