Red Lip Nerite Snail (Neritina sp.) 1-2cm

Overview

The Red Lip Nerite Snail (Neritina sp.) is a small, attractive freshwater snail prized for its algae-eating habits and distinctive red-marked mouthparts. At just 1-2cm on arrival, it is a compact and useful addition to established aquariums, helping to keep glass, décor and plant leaves tidy without becoming a nuisance breeder in freshwater. Nerites are among the most popular clean-up crew in the hobby because they are peaceful, hardy and visually appealing.

This species is best suited to mature aquariums with stable water conditions and a good supply of natural algae or supplemental grazing foods. Like other nerite snails, it is not a plant eater in the usual sense, but it will constantly browse biofilm, soft algae and detritus. It is an excellent choice for community tanks, aquascapes and shrimp setups where a gentle, effective algae grazer is desired. All livestock is packed carefully for fast UK delivery, and we offer a live arrival guarantee for peace of mind.

Because this is a live animal, please ensure your aquarium is fully cycled and suitable before ordering. Nerites are sensitive to sudden changes in water chemistry and do best in tanks with stable pH, adequate hardness and plenty of oxygenation.

Care at a Glance

Origin & Natural Habitat

Neritina species are found across tropical and subtropical regions, often in brackish estuaries, mangrove areas, rivers and streams where hard surfaces are covered in algae and biofilm. Many nerites naturally move between freshwater and slightly brackish environments during their life cycle, which is one reason they prefer mineral-rich, stable water in the aquarium. In the wild they spend much of their time grazing on rocks, roots and submerged wood, using their strong foot to cling tightly to surfaces in flowing water.

The Red Lip Nerite Snail is commonly kept in freshwater aquariums, where it adapts well provided the tank is mature and the water is not too soft or acidic. A harder, more alkaline environment helps support shell health and long-term vitality. Their natural grazing behaviour makes them especially useful in planted tanks, where they can help manage light algae growth without damaging healthy plants.

Tank Setup & Water Parameters

For best results, keep Red Lip Nerites in an established aquarium with stable filtration and good oxygenation. A minimum of 40 litres is recommended, although larger tanks are always better because they provide more grazing area and more stable water conditions. These snails are escape artists, so a secure lid is strongly advised, especially if the waterline is close to the top of the tank.

They thrive in temperatures between 19-26°C, with a pH range of 6.8-8.5 and moderate to hard water. The species is particularly well suited to community aquariums with mineral-rich water. Very soft or acidic conditions can gradually erode the shell, so if your tap water is naturally soft, consider remineralisation or a suitable buffering approach. A gentle current, clean substrate and plenty of hardscape, glass and plant surfaces will give the snail plenty to graze on.

Decor can include driftwood, stones, live plants and smooth ornaments. Nerites are not burrowers, so they spend most of their time on surfaces rather than in the substrate. They appreciate a tank that has had time to develop a natural film of algae and micro-organisms, though they will also accept supplementary foods if the tank is very clean.

Good water quality is essential. Avoid ammonia and nitrite completely, and keep nitrate as low as practical through regular maintenance. Stable parameters are more important than chasing exact numbers. When acclimating, drip acclimation is recommended to reduce stress from changes in temperature and mineral content.

Feeding Guide

Red Lip Nerite Snails are primarily algae grazers. Their natural diet consists of soft algae films, diatoms and biofilm found on glass, rocks and décor. In the aquarium they will happily work across the tank surfaces throughout the day and night, though they are often more active after lights out.

Do not rely on algae alone in a very clean aquarium. If the tank does not produce enough natural grazing, supplement with algae wafers, spirulina-based foods, blanched courgette, spinach or cucumber, and sinking vegetable pellets. Offer small portions and remove leftovers after a few hours to maintain water quality. They do not need high-protein foods as a staple, and overfeeding can quickly affect the tank.

Like all snails, they require calcium and other minerals to maintain a healthy shell. A hard-water setup is ideal, but in softer water you may need to provide mineral support through diet or water treatment. A healthy shell should be smooth and intact, without pitting or thinning.

Tank Mates / Compatibility

Red Lip Nerites are peaceful and best kept with calm community fish and invertebrates. They are suitable for many planted freshwater aquariums, including shrimp tanks, as they do not prey on healthy shrimp or fish. Their only real defence is their shell, so they should not be housed with species that nip, pick or eat snails.

Good tank mates include small tetras, rasboras, danios, Corydoras, Otocinclus, peaceful livebearers, dwarf gouramis in well-managed communities, and most freshwater shrimp. They also do well with other non-aggressive snails provided the tank is large enough and food is not limiting.

Avoid loaches, puffers, large cichlids, crayfish and any fish known to attack snails. Goldfish may also harass or eat smaller snails. If you keep active bottom dwellers, ensure there is enough food and surface grazing space so the nerite is not outcompeted.

One of the biggest advantages of nerite snails is that they do not reproduce in typical freshwater aquariums, so you will not get a population explosion. They may lay small white eggs on hard surfaces, but these do not hatch in freshwater. This makes them a tidy and manageable choice for aquascapes and display tanks.
