Clithon corona
A nerite snail whose shell bears a row of spiny projections. It rasps algae from hard surfaces. Being amphidromous, it will not reproduce within a freshwater aquarium alone.
Clithon corona is an operculate nerite snail living in both brackish and fresh water. The English Wikipedia gives a range across the Western Pacific and Southeast Asia, from the Philippines, Indonesia and Malaysia to Micronesia, Papua New Guinea, the Solomon Islands, Vanuatu, New Caledonia, Samoa, Taiwan, and Okinawa and the Ryukyus of Japan. It is an amphidromous benthic species found in freshwater rivers and brackish estuaries alike, grazing algae on hard substrates in intertidal zones and fast-flowing reaches. The freshwater hermit crab Clibanarius fonticola is known to use only the shells of this species. SeaLifeBase treats it as a benthic species of tropical brackish water and notes that the Neritopsina are generally gonochoric broadcast spawners whose embryos pass through planktonic trochophore and then veliger stages, which is why it cannot be bred through generations in fresh water alone. It is traded for freshwater aquaria.

Origin
Western Pacific and Southeast Asia (Philippines, Indonesia, Malaysia, Taiwan, and Okinawa and the Ryukyus of Japan)
Temperature
22〜28℃
Algae, biofilm and sinking prepared foods
Provide hard surfaces where algae can grow, whether glass, stone or driftwood. It sometimes climbs above the waterline and falls, so fit a lid and right any snail found upside down.

No verifiable pH, hardness or temperature figures exist for this species, so none are given. It is tropical and occurs in both brackish and fresh water, and the basic requirement is to avoid strongly acidic or very soft water, which erodes the shell.
Peaceful and harmless to other animals. Do not house it with snail-eating fish or with assassin snails. The spines make it a less easy target for snail-sucking fish, though not a safe one.
It rasps algae from hard substrates. It loses condition once the tank runs out of algae, so supplement with a sinking plant-based food or blanched vegetables.
It is amphidromous and its larvae are planktonic, so it does not reproduce within a freshwater aquarium. Even where spawning occurs, the larvae cannot complete their development in fresh water.
It grips hard surfaces strongly, so shift it gently with a spatula under the shell rather than prising it off. It cannot always right itself if turned over, so put it back when you find one. Never use copper-based fish medications, which are toxic to snails. It is not listed by CITES.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
Horned Nerite feeds on: Algae, biofilm and sinking prepared foods. Aim for a balanced diet with appropriate feeding frequency.
