Number of Nerite Snails vs Tank Gallon Size [Complete GUIDE]

Nerite Snails are stunning, vibrant creatures that will bring lots of excitement to your aquarium. However, being an aquarist, you should first have the ideal tank size sufficient for the movement and schooling of Nerite Snails.

Aquarists mostly get confused about how many Nerite Snails can fit in a 10-Gallon tank. Your aquarium will develop into a healthy ecosystem, and your Nerite Snail will have long and fulfilling lives if you make the right decisions.

Nerite Snails Tank Size Guide: How Many Nerite Snails Can You Keep in an Aquarium?

Despite the fact that a single Nerite Snail can remain alive in a 10-gallon tank, they thrive better in small groups and expand their space needs accordingly.

The maximum size of a Nerite Snail is 1 in length. They cannot grow substantially even if they are fully healthy or at full younger age.

As a general rule of thumb, a 10-gallon aquarium is enough for two Nerite Snails. You can house one Nerite snails in a 5-gallon tank, and 2 Nerite Snails in a 10-gallon tank; the 20-gallon aquarium can hold 4 Nerite Snails, a 60-gallon tank can hold 12, and a 75-gallon aquarium can hold 15.

On average, they have 1-3 years of life span in an aquarium.

The well-being of these stunning creatures depends on careful filtration and constant attention to water quality. You can make your Nerite Snails feel comfortable and thrive with the right room and care.

The life span of Nerite Snails

With the proper maintenance and a well-maintained tank, a Nerite Snail can live for up to 3 years in an aquarium. However, some people can extend their lives by five years or more with special treatment. Their lifespan can be affected by genetics, water quality, nutrition, and the general tank environment. Routine care, a nutritious diet, and a stress-free environment can ensure the health and lifespan of Snails.

Minimum tank size for Nerite Snails

 With greater room to swim and cleaner water, a 5-gallon tank is a minimum requirement for a school of a single adult Nerite Snails.

Nerite Snails are picky eaters, so a well-planted aquarium with hiding spots and territories is essential; a 10-gallon tank would be better for better nourishment, giving more room to do that job.

Types and colours of Nerite snails

  • Zebra Nerite is brownish in colour with black strips
  • Oliver Nerite is olive green in colour
  • Tiger Nerite as the name shown have yellowish or orange colour body with black strips
  • Dark brown or black colour with red or golden strips
  • Checkered Nerite is black and white in colour

Nerite Snails: Minimum Tank Size and Types

Aquarists love Nerite Snails for their beautiful colour and graceful motions in the tank. 

There is a large variety of Nerite Snail colours and patterns, with black, reddish brown, dark grey, dark green, and tan among the most common. 

In order to properly house a group of 4–8 of this Nerite Snail, a tank volume of at least 20 to 40 gallons is required.

How many Nerite Snails are in a 3-gallons tank?

A 3-gallon tank is not recommended for keeping Nerite Snails. The minimum tank size for keeping Nerite Snails is 5 gallons. If you don’t have enough room/tank to accommodate Nerite Snails, don’t try to endanger their life in small tanks. You can keep guppies in a 3-gallon tank.

Factors to Consider When Determining Tank Size for Nerite Snails

A few considerations exist when deciding the best tank size for your Nerite Snails. Snail characteristics include physical dimensions, activity levels, and social interactions with other fish.

Size of the Nerite Snail

Nerite Snails typically grows 1 inches; a 10-gallon tank is enough for two Narite snails. If you have space issues and are a snail lover, you can keep a single snails also in a 5-gallon tank. A 5-gallon tank is not bad for keeping snails.

Aggression level

Nerite Snails are very peaceful; they don’t have disputes for territories and have deficient aggression levels. Still, for factors of safety, you need to have proper supervision of the tank to have a large number of Snails in a tank.

Nerite Snails’ compatibility with other fishes:

Ideal Tank Mates of Nerite Snails:

When choosing tank mates for Nerite Snails, Choosing species of fish that thrive in similar water conditions and are not aggressive or territorial is important. Also, try to keep away from big fishes, which can you snail as food inside an aquarium.

Shrimps, Danios, Tetras, Ghost, Guppies, Charry, Snowball, and blue velvet are all examples of peaceful community fish.
The Nerite Snails should not be kept with any known aggressive such as barbs and several species of gouramis. Furthermore, it is recommended not to overload the aquarium since doing so can lead to poor water quality and the discomfort of the Snail.

Disease and treatment

Cracking of the Shell:

The shell of the Nerite snail may weaken or develop holes, and visible erosion or pitting may also be present.
Causes include insufficient minerals or acidity in the water.

Increase calcium levels using supplements or cuttlebone to treat and keep the tank at a stable pH level.

Parasitic Diseases:

Signs include a lack of energy, an inability to eat, odd behaviour, and the presence of external parasites.
The most common culprits are introducing diseased Nerite snails or plants or not keeping a clean tank.
In order to treat the Nerite snails, isolate them in a quarantine tank and provide drugs designed to kill the parasites.

Infection by Fungi:

Sluggishness, loss of appetite, and the appearance of white or fuzzy growth on the Nerite snail’s body or shell are all symptoms.
Causes include contamination of water, physical damage to the Nerite snail, and a lowered resistance to disease.
Modify the water in the tank, keep it clean, remove any infected Nerite snails, and treat them with antifungal drugs as instructed.

Bacterial Infection

The symptoms include ulcers or sores on the Nerite snail’s body or shell, discolouration, lethargy, and loss of appetite.
Injury, stress, and a weakened immune system are only a few causes of poor water quality.
Improve tank hygiene and water quality, quarantine diseased snails, and use antibiotics designed for aquatic snails to treat the infection.

Deficiencies in Nutrition:

The symptoms include slow development, irregular shell formation, compromised immunity, and loss of appetite.
The root of the problem is eating poorly or not getting enough of certain nutrients.
As a form of treatment, you can offer your Nerite snails a diet consisting of commercial snail food, algae wafers, blanched vegetables, and calcium-rich supplements if necessary.

How many Nerite Snails are in a 10-gallons tank?

Keeping a small school of Nerite Snails in a tank of 10 gallons is possible. However, keep in mind that these Nerite snails require a larger tank size, ideally 20 gallons or more.

Considering that an adult Nerite Snail is about 1 inch long, a 10-gallon aquarium might house about 2 Nerite Snails. The health of the Nerite snail depends on the availability of suitable hiding places, plants, and swimming areas. Maintenance of water systems and monitoring water quality metrics are also important for their well-being.

Setting Up the Ideal Environment for Nerite Snails

After settling on a tank size just right for your Nerite Snails, creating an atmosphere as close as possible to their original habitat is time. This includes giving them places to hide, a foraging-friendly substrate, and a clean environment in which to live.

Hiding Places

A more natural and peaceful atmosphere can be achieved by giving them plenty of places to hide.

Your Nerite Snails will appreciate the natural atmosphere you create with the help of live plants, pebbles, and driftwood.


while natural explorers, Nerite Snails, need a substrate that doesn’t restrict their movement while they look for food. A sandy or fine-gravel ground is advised to simulate their natural habitat best and encourage natural browsing behaviour.


Ensure you have enough plants in your tank to absorb the carbon dioxide, nitrate, and other toxic waste from the Nerite Snail excretion.

Nerite Snails can survive on their own with just plants and pests. So plantation is essential.


To grow, Nerite Snails need clean, well-filtered water. High-quality canisters or power filters with a flow rate of 6-8 times the tank volume per hour are recommended. To keep your filter running, choose and maintain one that fits your tank.


Nerite Snails need a steady and warm water temperature of 65-83°F. A high-quality submersible heater that fits your tank is crucial. To maintain a stable temperature, check the temperature using a thermometer and make adjustments.


Nerite Snails do not require intense lighting and may even prefer low to moderate levels of light.

Use 5 watts LED light which can save electricity as well as give you proper lighting.

Water Quality

Nerite Snails flourish in a certain set of water parameters. They prefer a pH range of 7 to 8, a water hardness of 7-9dGH, a salinity of 0-6 PSU, and a 65-83°F temperature range.

It is critical to keep water parameters consistent by making regular water changes and monitoring the tank’s water chemistry. Using a high-quality filter can also assist in maintaining.

How many Nerite Snails are in a 15-gallons tank?

A 15-gallon tank is recommended for keeping Nerite Snails. You can keep 3 Nerite Snails in a 15-gallon tank

Nerite Snails in a glass bowl

Can Nerite Snail live in a glass bowl?

Nerite Snails can successfully live in a Glass bowl, but this is not a recommended practice.

Keeping Nerite Snails in a glass bowl is not advised since this can harm their health.

Nerite Snails can only flourish in conditions where they have plenty of room to move, good water quality, and enough filtration.

Nerite Snails kept in glass bowls may suffer from poor water quality and other health problems due to the bowls’ tiny size, lack of filtration, and inadequate aeration.

This is why it’s crucial to supply your Nerite Snails with a clean, well-maintained tank of the appropriate size.

Single Nerite Snail in a tank

Nerite Snails like to live alone or in a small community, so you must use a small container of 5 gallons to have a single Nerite snail.

The male-to-female ratio of Nerite Snails in a tank

If you want to have both sexes in your tank, you can add maximum of 1 males with 1 females in a 10-gallon tank and 20 gallon tank can keep 1 Male vs 3 female.

Breeding of Nerite Snails

Nerite Snail breeding in an aquarium can be a fascinating and enjoyable experience. Here are some general breeding recommendations for Nerite snails:

Species Choice:

Select Nerite snail species are known to breed easily in aquariums. Mystery snails (Pomacea spp. ), and Ramshorn snails (Planorbidae family) are popular aquarium snail species for breeding.

Optimal Situation:

Create breeding circumstances that include adequate water parameters, temperature, and lighting. Research its specific requirements to guarantee that you meet the needs of the Nerite snail species you want to breed.

Identification of Male and Female:

Nerite Snails have male and female organs. They do, however, require a partner to reproduce. To determine probable male and female Nerite snails, look for morphological distinctions such as shell shape or size.

Hiding Places:

Nerite Snails frequently lay their eggs above the waterline or on aquarium surfaces. To increase egg deposition, provide a variety of hiding places such as rocks, driftwood, or plants.

Suitable Substrate:

Specific substrates are preferred by some Nerite snail species for egg-laying. Mystery snails, for example, deposit their eggs above the waterline, attaching them to hard surfaces such as aquarium glass or other things. Investigate the breeding habits of your chosen species and supply an adequate substrate.

Egg Care:

After laying eggs, it is critical to offer good care. To increase the odds of hatching, keep the eggs moist and undisturbed. To preserve water quality, keep an eye on the eggs and remove those that appear infertile or mouldy.

Hatching and Juvenile Care:

The juvenile Nerite snails will emerge once the eggs hatch. They may require particular attention as well as appropriate nutritional sources. Feed a well-balanced diet that includes algae, commercial snail food, and blanched vegetables. Maintain adequate water quality and consider isolating juveniles from adult snails to prevent predation or food rivalry.

Keep in mind that Nerite snails can reproduce quickly in suitable settings, and overpopulation could become an issue. Keep an eye on your Nerite snail population and take the necessary steps to minimize overcrowding, such as hand removal or altering feeding habits.

Diet of Nerite Snails:

The diet of Nerite snails can vary depending on the species. Here are some general guidelines for feeding snails:

  1. Algae: Nerite Snails eat algae. Make sure the tank has enough algae to feed them. If algae growth is low, feed them algae wafers or spirulina.
  2. Vegetation: NeriteSnails also enjoy consuming various types of vegetation. Offer blanched vegetables like spinach, zucchini, lettuce, or cucumber slices. These can be attached to a feeding clip or placed directly in the tank.
  3. Calcium-Rich Foods: Nerite Snails require calcium for proper shell development. A cuttlebone or calcium-enriched Nerite snail pellets ensure their shells remain solid and healthy.
  4. Commercial Snail Food: Specific commercial snail foods provide a balanced diet for snails. These foods often contain a mix of algae, vegetables, and essential nutrients.
  5. Avoid Overfeeding: Nerite Snails have a slow metabolism, so it’s important not to overfeed them and remove any uneaten food to prevent water quality issues.
