  • Black Racer Nerite Snail (Neritina juttingae): Black Racer Nerite snails are a solid black color. They are not as common as Zebra or Tiger Nerite snails, but they are still relatively easy to find. Black and red racer nerite snails are peaceful and effective algae eaters. They grow to be about 1 inch in diameter.
  • Horned Nerite Snail (Nerita albicilla): Horned Nerite snails have two small horns on their shells. They are not as common as Zebra Nerite snails or Tiger Nerites, but they are still relatively easy to find. Horned Nerite snails are peaceful and effective algae eaters. They grow to be about 1 inch in diameter.

These Nerite snails are peaceful and make great additions to freshwater aquariums. They are all effective algae eaters and help keep your tank clean.

However, it is essential to note that Nerite snails are not completely algae-dependent and will need to be supplemented with other foods, such as blanched vegetables if there are not enough algae in the tank.

Nerite Snail Care and Recommended Water Parameters for Keeping Nerite Snails

Nerite snails are popular aquarium pets due to their attractive shell patterns and ability to keep algae in check. Regarding care, nerite snails require a stable, clean environment with proper water parameters.

The recommended water parameters for keeping Nerite snails include a pH level between 7.5 and 8.5 and a water temperature between 72-78°F.

Additionally, it is essential to maintain a water hardness level between 5-12 dKH. It is crucial to avoid sudden changes in water parameters, as this can cause stress and even death in nerite snails.

Proper filtration and regular water changes are also crucial for maintaining a healthy environment for these creatures. Providing a smooth substrate and plenty of vegetation within the tank also benefits their well-being.

By maintaining the recommended water conditions and providing a suitable habitat, nerite snails can thrive and contribute to an aquarium’s overall health and aesthetics. 

Recommended Nerite Snail Tank Mates

When choosing tank mates for Neritidae snails, it’s essential to consider their delicate and non-aggressive nature. Some recommended tank mates for nerite snails include other delicate community fish such as tetras, Rasboras, and guppies.

These fish are unlikely to bother or harass the snails, making them suitable companions in a community tank. Other peaceful invertebrates, such as shrimp, cherry shrimp, or ghost shrimp, can also make good tank mates for Neritidae snails.

Just provide enough hiding spaces and plants for the shrimp to feel secure. Avoid keeping Neritidae snails with aggressive or larger fish that may threaten them.

Choosing tank mates with similar peaceful temperaments and environmental requirements will help create a harmonious and balanced aquarium ecosystem for the Neritidae snails and their companions.

Monitor the tank for any signs of aggression or stress, and be prepared to rearrange tank mates if necessary. 

Nerite Snail Eggs & Reproduction

Nerite snails reproduce by laying eggs, but they have unique reproductive behavior. While they can mate and lay eggs in an aquarium, the larvae that hatch from the eggs require brackish or marine conditions to develop correctly. This makes it challenging for hobbyists to breed Nerite snails successfully in a freshwater aquarium.

Here’s an overview of Nerite snail reproduction:

  • Mating: Nerite snails are dioecious, meaning they have separate male and female individuals. Mating usually occurs when a male snail releases sperm into the water, and a female snail takes in the sperm through her respiratory opening. Internal fertilization then takes place inside the female’s body.
  • Egg laying: After mating, the female Nerite snail will lay tiny, white, or translucent eggs. These eggs are usually laid on hard surfaces such as rocks, glass, or plants and attached firmly.
  • Brackish or marine development: The eggs of Nerite snails require brackish or marine conditions to develop into viable larvae. In freshwater aquariums, the eggs may not hatch or develop properly. Brackish water typically refers to water with a salinity level between freshwater and seawater.
  • Larval stage: Once the eggs hatch, tiny larvae called veligers emerge. The veligers are free-swimming and spend a couple of weeks in the water column before they develop into juvenile snails.
  • Return to freshwater: After the veliger stage, the juvenile Nerite snails must return to freshwater. In the wild, this is achieved by the currents carrying them.

Nerite Snail Lifespan, Size, Color & Tank Size

Nerite snails have a relatively long lifespan for an aquarium snail, living up to 2-3 years with proper care. These tiny snails typically grow to about 1 inch, making them a great addition to small and large tanks.

They come in various colors, including black, yellow, and olive, with intricate patterns on their shells. The optimal tank size for nerite snails is at least 5 gallons, as they are sensitive to water quality and need room to explore and graze for food.

It’s essential to provide a well-maintained environment with plenty of algae and biofilm for them to feed on and regular water changes to keep their habitat clean. With the right conditions, nerite snails can thrive and be a beneficial and attractive addition to any aquarium. 

Nerite Snails Algae Eating: Diet & Food Sources

Nerite snails are known for their voracious appetite for algae, making them popular choices for freshwater and saltwater aquariums. Their diet primarily consists of various types of algae, including diatoms, green algae, and brown algae.

In addition to algae, they may feed on biofilm, dead plants, and uneaten fish food. In aquariums, ensuring a constant supply of algae for Nerite snails to graze on is essential.

However, there is a shortage of algae. In that case, they can be supplemented with algae wafers, blanched vegetables such as zucchinis and cucumber, and commercial sinking pellets designed explicitly for herbivorous snails.

It is essential to provide a balanced diet for Nerite snails to ensure their overall health and well-being. Maintaining good water quality and proper tank maintenance are crucial to their success in a captive environment.

Overall, Nerite snails are efficient algae eaters and can significantly contribute to the overall cleanliness of an aquarium.
