Nerite Snail
Nerita spp.
The Nerite Snail is a highly effective algae grazer known for its ability to clean glass, rocks, and other hard surfaces. Its small size, attractive patterned shell, and constant grazing make it a valuable addition to marine aquariums.
Nerite Snails are especially useful for controlling film algae and diatoms, helping to maintain a clean and visually appealing tank.
Care & Temperament
- Difficulty: Beginner
- Temperament: Peaceful
- Adult Size: Up to 1 inch (2.5 cm)
- Minimum Aquarium: 10+ gallons
- Tank Placement: Glass / rockwork
- Activity: Active
Nerite Snails are hardy and adaptable, spending most of their time grazing on surfaces throughout the aquarium. They may occasionally venture above the waterline, so a secure lid is recommended.
Diet
The Nerite Snail is primarily herbivorous and feeds on various types of algae.
- Film algae
- Diatoms
- Algae on glass and rock surfaces
- Occasional supplemental algae wafers if needed
In tanks with limited natural algae, supplemental feeding may be necessary.
Tankmates & Compatibility
Nerite Snails are peaceful and compatible with most reef-safe fish and invertebrates.
Good tankmates include:
- Clownfish
- Gobies
- Blennies
- Other clean-up crew members
Use caution with:
- Wrasses that may prey on snails
- Crabs that may attack snails
Providing a peaceful environment helps ensure long-term survival.
Reef Safe
Yes
Nerite Snails are completely reef safe and will not harm corals or other invertebrates.
Suggested Parameters
- Temperature: 24–27°C (75–81°F)
- Salinity: 1.024–1.026
- pH: 8.0–8.4
- Alkalinity: 7–11 dKH
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Nitrate: Ideally below 10–20 ppm
Stable water conditions are important for maintaining shell health and activity.
What You Are Buying
You are purchasing one Nerite Snail (Nerita spp.). Shell patterns and coloration may vary between individuals.
Health & Acclimation Notes
- Acclimate slowly using drip acclimation
- Ensure a secure lid to prevent escape
- Provide sufficient algae for grazing
- Avoid sudden parameter changes
Why We Love It
The Nerite Snail is an excellent algae cleaner, especially for glass and hard surfaces. Its efficiency, small size, and attractive shell make it a must-have member of any marine clean-up crew.
Collapsible content
LIGHT
LOW: Place coral at the bottom of the tank. Depending on the type, coral may need to be placed off sand and therefore mounted on a ceramic disc of piece of rock.
MEDIUM: Place coral at mid-range of the tank. Best placed/glued on top of a rock scape at mid-range height.Â
HIGH: Place coral from mid range to just below water level. SPS coral are shallow growing so they require and are able to tolerate intense light.
FLOW
LOW: Most soft coral do well with a small, gentle pulse. There are certain corals that can even be placed in areas of indirect flow, meaning places aside a rock structure or set into a entrance to a cave style space.
MEDIUM: Many LPS types of coral prefer medium pulse current. Most Euphyllia or corals that have more tissue structure connected to their skeleton, don’t like to be in a high flow area like the direct flow of the wave pump.
HIGH: Similar to high light, SPS enjoy being in some heavy current. Most LPS and SPS that branch encrust or plate prefer high flow that simulates the top water waves.
SKILL
ENTRY: While some may say beginner level, "Entry" is a good term to be used when starting out in the world of corals and marine life. Prior to adding livestock, you want to ensure that your reef has the proper parameters including zero levels of ammonia and nitrite. Seeing traces of nitrate in your waters is a good sign - just keep them at a lower level of 2ppm to 10ppm. Maintaining correct temperature and salinity are a huge factor to stable parameters. Starting to monitor your PH, alkalinity, calcium and magnesium is a great habit to get into to keep a successful reef.
While some soft coral don’t require too much light, having a proper reef light that puts out the proper pars is very important. You'll also want to have a good amount of flow and protected rock areas, as placing corals in their happy spot is ideal for success.
