Freshwater aquarium hobbyists often seek to add a diverse range of aquatic life to their tanks.

Characteristics of Nerite Snails

Nerite snails are a popular choice for freshwater aquarium hobbyists for several reasons. First and foremost, they are low maintenance creatures and require minimal attention from their owners. They can thrive in a variety of water conditions and can survive in tanks with or without a filter.

The size of nerite snails varies, with most species growing up to an inch in length. They come in different colors and patterns, including zebra stripes, dots, and swirls. Their unique patterns make them an attractive addition to any aquarium.

One unique characteristic of nerite snails is their ability to move in any direction, including upside down. They do not have lungs but breathe through gills, which allows them to stay underwater for extended periods. They have a hard, calcium-based shell that protects their soft body, and they can retract into their shell when threatened.

Curious Facts About Nerite Snails

They are algae eaters

One of the most significant benefits of nerite snails is that they are excellent at cleaning up algae in the aquarium. They will tirelessly graze on any algae growth, including diatoms, green spot algae, and hair algae. They will also help to prevent the growth of new algae by consuming the spores before they can grow.

They lay eggs everywhere

If you have nerite snails in your aquarium, you will likely see tiny white or beige eggs stuck to various surfaces. These eggs are incredibly adhesive and challenging to remove. Although they are not harmful, they can be unsightly and may require some effort to clean up.

They can be picky eaters

While nerite snails will eat most types of algae, they can be picky eaters when it comes to other types of food. They may refuse to eat certain types of fish food, and it is crucial to ensure that they are receiving a balanced diet. A lack of proper nutrition can lead to health problems such as a weakened shell.

They are popular in aquascaping

Nerite snails are often used in aquascaping, which is the art of creating underwater landscapes in aquariums. Their unique patterns and colors make them an attractive addition to any aquascape. They also help to maintain a healthy environment by consuming algae and detritus.

As most planted tanks are not covered, it may become a challenge to stop them from wandering out of the aquarium. Thankfully, there are products that help you to stop them from escaping like the Glasgarten Snail Safe that can be safely placed around the edge of the aquarium acting as a physical barrier that does not harm the snail.


Nerite snails are fascinating creatures that offer several benefits to freshwater aquariums. They are low maintenance, algae-eating machines that can thrive in a variety of conditions. While they may be picky eaters and lay eggs everywhere, their unique patterns and usefulness make them a popular choice for aquarium hobbyists. Consider adding some nerite snails to your aquarium and enjoy their many benefits.

The Bros are back!


We have received a very limited but beautiful selection of Brotia snails. These peaceful live-bearing snails are some of the larger snails that you can have in a freshwater tank (their full size may exceed 7cm). Both species are considered to be plant-safe and are a treat to the eye! 🙂

They love a good piece of wood and leaf litter to match and thrive on eating Aquapoda 100% Natural Premium Food Sticks and love a good soft paste food.

Take a look for yourself below and follow the links at the bottom of this post to read more about them.

A very limited amount (<5) of each species is available from our online shop – Brotia herculea and Brotia pagodula.
