How To Breed Nerite Snails? Helpful Guides For Aquarists

When kept alongside tiny, calm fish, Nerite snails are fantastic additions to your saltwater and freshwater aquarium.

Due to their minimal feeding and water habits, these snails are relatively hardy and straightforward to care for.

Although it’s common knowledge that these aquatic creatures are simple to breed, this species presents a little challenge.

How to breed Nerite snails? This article will show you the complete guides for aquarists of all levels. Let’s check it out!

How To Breed Nerite Snails?

Snails can also survive in saltwater and freshwater, but they prefer to only reproduce in saltwater.

If you plan to reproduce these aquatic creatures successfully, keeping them in salty water or an aquarium with saltwater is better.

These crawlers will produce more successfully if you provide them with a habitat similar to their natural environment. 

If you already have a tank with saltwater, you can introduce some snails into this container. 

It’s best to keep at least 5 to 6 creatures in the same aquarium for a better chance of breeding. 

Experts recommend you have several snail groups in a shared tank if you can’t determine whether they are female or male Nerites to breed successfully. 

The female Nerite will begin searching for driftwood or leaves to deposit her eggs on if she is successful in finding a mate, and the breeding process starts.

She may lay her eggs on the shells of other snails. The egg shells are yellow when first released, becoming black as the young crawler grows.

The oval form of an eggshell may expand 1.5mm in length and 1mm in breadth.

A delicate membrane protects the shell. Each capsule may contain around 68 eggs or up to 106. 

The capsule will transform into a larva after three days. After seven days, it may turn into a baby crawler. 

These babies are tiny and may be sucked into the filtration system. Be careful to care for these miniature creatures.

How Can You Tell If A Nerite Snail Is Male Or Female?

Unlike other snail species, these crawlers do not reproduce asexually. Due to the dimorphism of this species, reproduction requires both females and males.

Nevertheless, it’s relatively challenging to distinguish between Nerite females and males regardless of what you refer to on some websites.

The general concept is that a female is slightly bigger than a male. Yet, this way isn’t helpful as you may get confused between a juvenile Nerite female and a male. 

Although this is not an expensive error, it might be annoying if several crawlers that you purchase belong to the same gender.

Additionally, you may search for dissimilarities in color, but this method won’t get you very far.

The best solution is to seek help from professionals to eliminate any doubt. 

Buying your pets from famous and trustworthy stores would be best. Besides, get specific specimens depending on the gender you want.

How To Care For Baby Nerite Snails?

After transferring baby Nerite snails into another tank, it’s time to learn how to care for them. Let’s follow the guides below!


Algae growing in the aquarium is typically the preferred meal for these aquatic creatures.

If algae are sufficient in your aquarium, you will watch your snails actively consuming this food.

However, you must control algae growth in your tank as these organisms tend to develop quickly. 

When algae don’t grow fast enough for your crawlers, you may provide them with algae wafers. It’s a simple, affordable, and efficient way to feed your pet crawler.

Besides, you can feed your pets other food sources such as cucumber, broccoli, beans, or spinach for more required energy. 


Tank Conditions

Water parameters:

If you prefer to extend the life of your pets, it’s vital to consider the water factors. It’s best to create appropriate water conditions to make your pets active. Although they are hardy, you must establish suitable tank habitats. 

  • Temperature: 72 – 78℉
  • Water hardness: 6 to 12 dKH
  • pH level: 7 to 8.5

If you follow these water parameters, these aquatic creatures will actively move in your aquarium. 

Tank size:

A tank of at least 10 gallons will be suitable for a Nerite. If you want to keep more than one, consider increasing the size by around five gallons. 

Keeping many crawlers in a tank means they will generate more waste. It is a significant matter for restricted aquariums. 

Tank decoration:

These creatures will be healthy if you keep them in an aquarium similar to their natural habitat.

You can add rocks, crannies, nooks, driftwood, and substrate as decorations to your aquarium.

Can Nerite Snails Reproduce In Freshwater?

The short answer is no! These creatures prefer to reproduce in salty water for better results. 

Do Nerite Snails Need Brackish Water To Breed?

Yes! It would be best if you put these crawlers in salty water to breed successfully. These water conditions mimic their natural living habitats. 

Can Nerite Snails Reproduce Asexually?

These creatures don’t generally reproduce asexually like other aquatic crawler species. The Nerite female will lay eggs, and the male will fertilize them like fish. 

Will A Single Nerite Snail Lay Eggs?

The bad news is no! The breeding of this species requires both two sexes: Males and females. Thus, a female can’t lay eggs itself. 

Do Nerites Need A Filter?

Absolutely yes! These aquatic creatures are vulnerable to unhealthy and harmful levels of ammonia and nitrates

For this reason, you must install an active filtration system in your aquarium.
