Horned Nerite

Horned Nerite key facts

Care level

Beginner-friendly

Lifespan

3-5 years

Diet

Algae, biofilm and sinking prepared foods

Tank

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.

Water Temperature & Quality

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.

Tank Mates

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.

Diet & Feeding

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.

Breeding & Spawning

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.

Health & Notes

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.

About Horned Nerite

A spiky-shelled nerite snail that grazes algae off glass and driftwood, valued as a natural tank cleaner. Its amphidromous life cycle means it won't overpopulate a freshwater tank, making it easy for beginners.

7 things to know before welcoming a Horned Nerite

1. 1A Reliable Algae Cleaner

   Horned Nerites graze algae off glass, driftwood, and rocks, making them popular for natural tank cleanup. Their grazing habit is one of their most valued traits among keepers.

2. 2Won't Overpopulate Your Tank

   This species has an amphidromous life cycle, meaning its larvae need conditions beyond fresh water to develop. As long as it's kept in a freshwater tank, it won't multiply out of control.

3. 3Watch for Escapes

   Nerite snails are known for climbing out of tanks. Keep a secure lid on and maintain the water level below the rim to help prevent escapes.

4. 4Can Get Stuck Upside Down

   Due to its shell shape, this snail can sometimes struggle to right itself if flipped over. If you notice one stuck, gently turn it back over.

5. 5Acclimate Slowly

   This snail can be sensitive to sudden shifts in water parameters. Take your time acclimating a new arrival to minimize stress from the change in environment.

6. 6Plays Well With Others

   Its calm temperament means it rarely bothers fish or shrimp. This makes it easy to add to a community tank for algae control.

7. 7Prepare Your Tank First

   It settles in more easily in a tank that already has some algae growth to graze on. Check how established your tank is before bringing one home.

Frequently asked questions about Horned Nerite

Q.Will it breed in my tank?

A.Horned Nerites have an amphidromous life cycle, so their larvae need conditions beyond fresh water to develop. Kept in a freshwater tank alone, they're very unlikely to overpopulate.

Q.Can it live with other fish or shrimp?

A.Yes, its calm temperament means it rarely bothers tankmates. It's commonly added to community tanks to help control algae.

Q.What should I do if it gets flipped over?

A.Because of its shell shape, it can sometimes struggle to right itself. If you notice one stuck upside down, gently turn it back over.

Q.Can it escape from the tank?

A.Nerite snails are known for climbing out of tanks. A secure lid and a water level kept below the rim can help prevent this.

Q.What does it eat?

A.It mainly grazes on algae growing on glass, driftwood, and rocks. It's often kept specifically for algae control in the tank.
