Nerite Snail

Nerite snails ( Nerita / Neritina spp.) are small cleaning snails that are surprisingly effective considering their size. Their rounded, colorful shells—often decorated with zebra, tiger, or dotted patterns—also make them visually appealing. They are particularly known for their effectiveness against stubborn algae such as diatoms and encrusting algae on glass.

His role in the baccalaureate

These are the ultimate window and surface scrapers. Their scraping action leaves characteristic zigzag marks on glass—a sign of active and effective cleaning. They are very useful in nano-reefs where their small size is an advantage.

Recommended conditions

• Temperature: 23–27°C
• Salinity: 1.023–1.026
• pH: 7.8–8.4 (normal natural day/night fluctuation in a reef tank)
• Alkalinity: 8–10 dKH — Calcium: 380–430 ppm

Behavior

Active day and night. Right themselves if overturned. Do not usually reproduce in marine aquariums (pelagic larvae require freshwater for development). Very peaceful.
