Providing a varied diet to ensure snails receive all the necessary nutrients to thrive is crucial. Additionally, proper feeding schedules and portion control are essential for maintaining a healthy environment for these snails.

By following the advice in this care guide, you can support the health and well-being of your nerite snails, creating a vibrant and balanced ecosystem within your aquarium. 

What do Nerite Snails Eat?

Nerite snails are one of the most popular species of aquatic snails. They are unique because they are one of the few species that can live in both fresh water and marine environments.

These tiny snails are herbivores, primarily eating algae in your tank. If there is not enough algae to graze on, they may starve to death.

Nerite Snail Lifespan

It is easy to take care of nerite snails, as they will clean algae from the tank and won’t eat leftover fish food so that they won’t contribute to the waste in the tank. They are often referred to as an “algae eater.”

Freshwater and marine nerite snails have unique patterns and colors, such as the zebra nerite or black racer. If you are trying to feed your nerite snails, you can offer them algae wafers or even blanched green beans to ensure they get enough calcium.

It is essential to consider the tank’s water temperature, substrate, and waterline to create a suitable environment for them to reproduce. Having at least one male and one female nerite snail is recommended to lay eggs successfully and produce larvae.

Nerite Snail Food List: (Best Food for Nerite Snails)

Nerite snails are famous aquarium residents known for their voracious appetite for algae. While they’re excellent at keeping your tank clean, there might need to be more algae for them to thrive. Here’s a list of the best food options for your nerite snails:

Natural Food for Nerite snails:

  • Algae: Their primary food source. They’ll happily munch on various types of algae, including hair algae, green dust algae, brown algae, and even black beard algae. 
  • Blanched vegetables: Offer blanched zucchini, spinach, kale, or carrots as a tasty treat. Remove uneaten portions after a day or two to prevent water quality issues. 
  • Indian almond leaves: Provide essential nutrients and tannins, promoting good health and breeding. 

Commercial Snail Foods:

  • Algae wafers: A readily available source of nutrients, perfect for tanks with limited algae growth. Choose algae wafers specifically formulated for snails or plecos. 
  • Snail pellets: Formulated with essential vitamins and minerals to supplement their diet. 
  • Spirulina flakes/powder: Rich in protein and vitamins, ideal for boosting their health and growth. 

Providing a varied and nutritious diet ensures your nerite snails stay healthy and happy in your aquarium.

Nerite Snail Feeding In Tank (Behavior & Tank Mates)

Nerite snails are herbivores known for their unique feeding behavior in the tank. Small invertebrates are often kept in freshwater aquariums, but some species can also thrive in saltwater or brackish water.

When it comes to feeding, they can be seen grazing on algae and other organic matter that accumulates on the surfaces of the tank, such as glass, live plants, and even driftwood.

As tank mates, nerite snails are compatible with various fish and invertebrates, including shrimploach, and other small freshwater fish.

However, it is essential to note that they should not be kept with any fish or invertebrates known to prey on snails, as this can lead to an unhealthy or dead population of snails in the tank.

When feeding them, putting a smaller portion of blanched zucchini slices or canned green beans is crucial to ensure the wafer, used to supplement their diet, doesn’t pollute the water.

Additionally, maintaining good water quality and keeping the tank free from unhealthy or dead vegetation will ensure the overall health and well-being of the nerite snails.

As hermaphroditic creatures, nerite snails can reproduce asexually but often require a mate. If conditions are right, they may lay egg capsules on hard surfaces in the tank, which can develop into young nerite snails.

However, these nerite snail eggs are often difficult to hatch in a home aquarium, and most will only survive if they are in salt water, where they would typically hatch. Their larvae would empty into the ocean to develop shells before returning to freshwater or salty conditions.

How to Set Up an Aquarium for Nerite Snails

Setting up a tank for them isn’t difficult, but some key factors will contribute to their happy and healthy life. Here’s a guide:

Tank Size and Setup:

  • Size: Nerites can adapt to a wide range of tank sizes, but 5 gallons is the minimum for a single snail. Aim for 10 gallons if you plan to keep more. Each additional snail needs roughly 5 gallons.
  • Substrate: While not essential, crushed coral substrate can help maintain pH and hardness levels preferred by nerites. Gravel or sand works, too, but adding a cuttlebone is recommended for calcium.
  • Décor: Provide plenty of hiding places like rocks, driftwood, or caves. Nerites also appreciate surfaces to graze on, so include smooth rocks, plants, or decorations.
  • Filtration: A gentle filter is needed, but avoid strong currents that can stress the snails.
  • Water: Aim for a pH between 7.0 and 8.5 and moderate hardness (dH 12-18). Stable water parameters are crucial.

Important Considerations:

  • Algae: Nerites primarily feed on algae. If your tank lacks algae, supplement their diet with blanched vegetables like spinach or algae wafers.
  • Calcium: Nerite shells require calcium for growth and repair. Crushed coral, cuttlebone, or calcium supplements can help.
  • Temperature: Maintain water temperature between 65 and 85 degrees Fahrenheit.
  • Lid: Nerites can climb, so ensure your tank has a secure lid.
  • Tankmates: Choose peaceful fish like rasboras, tetras, or Corydoras. Avoid loaches, puffers, or aggressive fish that might prey on the snails.

Additional Tips:

  • Quarantine new snails before adding them to your main tank to prevent introducing diseases.
  • Monitor water quality regularly and perform water changes as needed.
  • Nerites generally don’t breed in freshwater, so population control shouldn’t be a concern.

Following these guidelines can create a happy and thriving environment for your nerite snails.

What Do Different Types of Nerite Snails Like To Eat?

The Neritidae family consists of many species of nerite snails, each with its own preferences regarding food. Some, like tiger nerites, are particularly fond of green spot algae and cyanobacteria, which they can find in their natural habitats along coastlines.

Others may prefer to feed on saprolegnia or detritus that commonly sprout in their mangrove habitat. In a tank or other fish environment, most nerite snails will happily consume green water algae and detritus, acting as a scavenger to keep the tank clean.

When keeping one or two snails, offering a smaller portion in the tank is essential, as they can only reach about 1 inch in size.

Additionally, it’s important to note that male and female nerite snails are required for breeding, so it’s best to keep them in quarters and put a smaller number of each sex in the tank to avoid overpopulation.

Black racer Nerite snail food: Black racer Nerites primarily feed on algae and biofilm in the aquarium. They may consume decaying plant matter and occasionally graze on soft algae-covered surfaces.

Olive nerite snail food: Olive Nerites primarily feed on algae and biofilm in the aquarium. They may consume decaying plant matter and occasionally graze on soft algae-covered surfaces.

Feeding Tips When Breeding Nerite Snails

While Nerite snails are excellent algae eaters, breeding them in fresh water is challenging. They require salty water (a mix of fresh water and salt water) to produce successfully. Therefore, any specific feeding tips regarding breeding won’t apply in a freshwater environment. However, I can offer some general feeding advice for Nerite snails:


  • Algae: Nerites are voracious algae eaters, happily munching on various types like green spot, hair, brown, and even black beard algae. If your tank has sufficient algae growth, additional feeding might not be necessary.


  • Blanched vegetables: If algae are scarce, offer boiled or steamed veggies like zucchini, spinach, kale, or carrots. Ensure they are pesticide-free and cut into small pieces.
  • Algae wafers: These provide nutrients and algae-mimicking elements. Opt for ones without copper, which is toxic to invertebrates.
  • Calcium-rich foods: Snails need calcium for shell growth. Consider crushed coral substrate, cuttlebone, or specific calcium supplements for your tank.

Additional Tips:

  • Variety: Offer different food options to cater to their preferences.
  • Placement: Place food near hiding spots for shy snails.
  • Removal: Remove uneaten fish food after a few days to prevent water quality issues.
  • Observe: Monitor their eating habits and adjust the feeding based on their activity and tank conditions.

Alternative Breeding:

If you’re interested in breeding Nerite snails, you’ll need a separate brackish water tank with specific parameters and conditions. This setup requires additional expertise and isn’t recommended for beginners.

Remember, I cannot provide personalized advice on breeding Nerite snails in freshwater as it’s impossible. However, if you want to learn more about brackish water setups and the intricacies of producing specific snail species, feel free to ask!

Common Problems with Nerite Snails

Common Problems with Nerite Snails include migration, a preference for tap water, and a tendency to cling to surfaces. Nerite snails are known to constantly migrate within the tank, which can lead to them climbing out of the water and potentially drying out.

Additionally, nerites prefer to lay their eggs in salty water, so they may not reproduce effectively in a freshwater environment. Another common problem with nerite snails is their habit of clinging to various surfaces in the tank, such as the glass or decorations.

This can be troublesome when trying to move or clean the tank, as the snails can be difficult to dislodge without potentially harming them.

Lastly, the shells of nerite snails are known to eventually break down over time, which can lead to health problems for the snails and potentially affect the overall aesthetics of the tank.
