Horned Nerite Snails are a tropical freshwater species of aquarium snail. They are easily identified by the multiple dark horns that protrude from their shell. The shell is yellow in color with thick black swirls along the edge. They are popular algae eaters and debris removers.

Most notably they will keep your glass crystal clear. They are available to purchase at most LFS or from other hobbyists. Horned Nerite Snails are popular and pricier than other snails because they are impossible to breed in freshwater. Nerite snails can grow up to 1" but adults are more commonly found between 1/2 and 3/4" in size. Horned Nerite Snails can also be used in outdoor ponds for similar purpose.

Horned Nerite Snails are avid consumers of aquarium algae and are useful in keeping the nitrates under control in an aquarium. They will keep the glass and substrate relatively clean, aiding the water changing and substrate vacuuming process. Horned Nerite Snails are peaceful creatures. They can be kept with other non aggressive fish, snail and shrimp species without problem.

Horned Nerite Snails are known as a species of 'tidal snail'. The name comes from the ability of the snail to live out of the water for prolonged periods of time. Unfortunately it is not uncommon for Horned Nerite Snails to escape. They are fairly easy to find and can be picked up and placed back into the aquarium. It is encouraged to keep a daily eye on Horned Nerite Snails

Temperature ~75°F

The optimum aquarium temperature for Horned Nerite Snails is around 70°F - 80°F (21°C-27°C).

pH ~7 | Hardness 7

Horned Nerite Snails require pH between about 6.5 and 8. Relative water hardness for Horned Nerite Snails should be in the range of 6-12dH. Horned Nerite Snails are hardy species and are able to withstand captivity fluctuations.

Max Size ~1"

Horned Nerite Snails can grow up to 1" but are often found at a maximum size of 3/4". They are suitable for medium sized aquariums.

Nitrite 0ppm

Nitrite should always be 0.

Ammonia 0ppm

Horned Nerite Snails are sensitive to ammonia spikes.

Nitrate >40ppm

Nitrates should be as close to 0ppm as possible. Horned Nerite Snails consume debris contributing to lower nitrates.

Stocking Guide

Horned Nerite Snails are excellent at consuming debris and algae. However in large numbers they will require extra food. For this reason it is wise to stock no more than one snail for every 4 gallons of aquarium water. Horned Nerite Snails have a short captive life of approximately one year. For this reason it is wise to slowly re-purchase snails throughout the year as Horned Nerite Snails cannot reproduce in freshwater.

Feeding

Horned Nerite Snails can simply be fed commercial flake and pellet food. They only require supplemental feeding if there is no debris or algae left to consume. They are efficient cleaners and will leave the glass and substrate very clean. They are not fussy eaters. The filter should be turned off during feeding to allow the food to float to the substrate where it is easily accessible for the Horned Nerite Snails.

Breeding

Horned Nerite Snails will not breed in freshwater aquariums. Horned Nerite Snails will only breed in brackish waters and even then raising young is difficult. Young successfully raised in captivity have far lower life expectancies than those wild caught. On the upside, Horned Nerite Snails will not overpopulate the aquarium making them far easier maintenance than other species.

Latest on Snails

Red Widow Rennschnecke (Vittina waigiensis)

Vittina waigiensis is a nerite snail kept for its grazing activity and striking red shell forms. It is generally peaceful, plant-safe and suited to mature freshwater aquariums with stable, mineral-rich water. Like other amphidromous nerites, it may lay eggs in freshwater, but its larvae normally require brackish or marine conditions, so routine freshwater breeding is not expected. The trade name “Red Widow” may cover a selectively colored form rather than a formally recognized taxonomic variety.
Red racing snail (Vittina waigiensis)

The red racing snail, Vittina waigiensis, is a striking nerite kept mainly for grazing algae from aquarium glass, rocks and decor. Adults are generally peaceful, plant-safe and suited to mature freshwater aquariums, but successful captive breeding is uncommon because the larvae require different conditions from the adults. Shell colors and markings vary considerably, and trade names can overlap with other nerite species, so identification from appearance alone is not completely certain.
Mixed Aquarium Snails: Algae Eaters and Clean-Up Crew

This mixed snail selection appears to include nerite-type algae grazers, ramshorn snails, and possibly Malaysian trumpet snails. Exact species and proportions cannot be confirmed from the supplied images, so care requirements may differ between batches. These peaceful invertebrates consume algae, biofilm, leftover food, and detritus, but they still need stable, mineral-rich water and responsible population management.
Red and Yellow Stripe Rennschnecke (Vittina waigiensis)

Vittina waigiensis is a striking nerite snail recognized by a rounded shell with red, yellow, orange, and dark patterning. It is primarily a freshwater grazer as an adult but has a life cycle that normally requires brackish or marine conditions for larval development. This makes it suitable for planted aquariums without normally becoming numerous. The supplied trade name and images are consistent with this identification, although shell patterns overlap among Vittina and related nerite species, so visual identification should be treated as provisional.
Ramshorn Snails Mix Rainbow

Rainbow ramshorn snails are a mixed-color freshwater aquarium form sold under a trade name rather than a single precisely identified species. The pictured animals have the characteristic planispiral shell and include blue, pink, pale and orange-red forms. They are peaceful scavengers that graze on biofilm and leftover food. Exact species and strain lineage cannot be confirmed from the supplied images alone, so care guidance is provided for commonly kept aquarium ramshorn snails.
Predatory Snail: Clea helena (Anentome helena)

Clea helena, also widely sold under the name Anentome helena, is a freshwater predatory snail from Southeast Asia. Its banded, cone-shaped shell and active hunting behavior distinguish it from common algae-grazing snails. It feeds mainly on other snails but also accepts meaty foods and carrion. In a mature aquarium it is generally safe with healthy plants, although it can reduce or eliminate desirable snail populations. Identification and classification may vary between sources, so both commonly used scientific names are included.
Pointed Mud Snail (Lymnaea stagnalis)

Lymnaea stagnalis, commonly called the pointed mud snail or great pond snail, is a freshwater pulmonate snail found in quiet, vegetated waters. Its tall, pointed shell and ability to breathe atmospheric air make it distinctive in aquaria. It can be a useful scavenger, but it reproduces readily when food is abundant. The supplied images are broadly consistent with this species, although photographs alone cannot confirm identification with complete certainty.
Pond post horn snail (Planorbarius corneus)

Planorbarius corneus is a European freshwater ramshorn snail found in ponds, lakes, marshes and slow-moving waters. Its large, planispiral shell and dark body make it a distinctive aquarium inhabitant, although the common name can be confused with other ramshorn snails. It is generally peaceful, useful as a scavenger and algae grazer, and manageable when food supplies are controlled.
Pimpled Lace Snail (Melanoides granifera)

The pimpled lace snail, Melanoides granifera, is a burrowing freshwater snail from the family Thiaridae. It spends much of its time in substrate, emerging to graze on biofilm, detritus and leftover food. Its ridged, patterned shell adds interest to planted aquariums, while its live-bearing reproduction can gradually increase its numbers. It is generally peaceful and plant-safe when adequately fed, but should be kept under observation because identification and appearance can vary among imported aquarium stock.
Pink ramshorn snail (Planorbella duryi duryi)

The pink ramshorn snail is a freshwater planorbid recognized by its flat, coiled shell and pink to reddish body. The supplied name identifies it as Planorbella duryi duryi, a subspecies associated with the southeastern United States, although shell color alone cannot confirm an exact identification. It is peaceful, air-breathing, and useful as a scavenger in planted aquariums. Like many ramshorns, it can reproduce quickly when excess food and organic debris are available.
Piano Snail (Taia naticoides)

Taia naticoides is a freshwater, live-bearing snail sold under names such as piano snail. It has a rounded, banded shell and is valued as a grazer of algae and aquarium biofilm. The supplied photographs resemble this trade identification, but images alone cannot confirm species, age, or whether the specimen is a juvenile. Good calcium availability, stable alkaline water, and regular access to natural or supplemental food are important for long-term care.
Piano Snail (Taia naticoides)

The piano snail, also sold as the brush algae snail, is a large freshwater operculate snail with a rounded, banded shell. Taia naticoides is associated with Southeast Asian freshwater habitats and is valued for grazing surface growth and consuming organic debris. Aquarium identification can be complicated because common names are applied inconsistently; confirm the species with a reliable supplier. It is generally peaceful, plant-safe and live-bearing, but it needs mineral-rich water and should not be treated as a solution for heavy algae growth.
Orange Track Racing Snail (Vittina semiconica)

The Orange Track racing snail, Vittina semiconica, is a freshwater nerite valued for algae grazing and its patterned orange shell. It is generally peaceful, plant-safe and suitable for established community aquariums. Identification from shell pattern alone can be difficult because several Vittina and related nerite species resemble one another, so the supplied trade name should be treated as provisional unless confirmed by a specialist examination.
Orange Rock Snail (Orange Tylomelania)

The Orange Rock Snail is a trade name commonly used for orange-bodied Tylomelania, a group of freshwater snails associated with Sulawesi. Its dark, strongly ridged shell contrasts with the bright orange foot and head. Exact species identification is uncertain from the trade name and photographs alone, so care should follow general Tylomelania requirements. These snails are peaceful, active mainly at night, and best kept in mature, warm, alkaline aquariums with stable mineral content.
Orange Red Ramshorn Snail (Planorbella duryi duryi)

The orange red ramshorn snail is a freshwater planorbid recognized by its flat, coiled shell and brightly colored body. Planorbella duryi duryi is associated with freshwater habitats in the southeastern United States, especially Florida, although aquarium specimens may be selectively bred and their exact locality is often unknown. It is generally peaceful, useful as a grazer and scavenger, and capable of reproducing quickly when food is abundant.
Midnight Lady Snail (Vittina sp.)

The Midnight Lady Snail is a dark, patterned nerite sold under the aquarium trade name Midnight Lady Schnecke. It is identified here as Vittina sp., because the exact species cannot be confirmed from the supplied name and photograph alone. These snails are generally peaceful algae grazers for mature freshwater aquariums, but successful breeding requires conditions that are not normally present in freshwater tanks.
