Zebra Nerite Snail

Zebra Nerite Snail (Neritina natalensis) – Description & Care Guide

The Zebra Nerite Snail is a small, attractive freshwater (and brackish) snail prized for its excellent algae-cleaning abilities and striking striped shell pattern. Hardy, peaceful, and low-maintenance, it's a favorite in aquascaped and planted tanks.

Basic Description

• Scientific Name: Neritina natalensis

• Common Names: Zebra Nerite Snail, Tiger Snail, Nerite Snail

  • Shell features black and yellow or gold striped, zebra-like markings

  • Small, rounded shape with a smooth operculum (trapdoor)

Diet & Feeding

• Natural Diet: Herbivore

  • Primarily grazes on soft algae (green film, diatoms)

• Supplemental Feeding (if algae is scarce):

  • Algae wafers

  • Blanched vegetables (zucchini, spinach, cucumber)

  • Spirulina-based foods

• Feeding Frequency: As needed—usually self-sufficient if algae is present

Care Tips

• Shell Health: Requires calcium-rich water to prevent shell erosion or pitting. Use:

  • Crushed coral substrate

  • Cuttlebone

  • Liquid calcium supplements

• Cleaning: Excellent at keeping glass, rocks, and decorations algae-free

• Behavior: Very peaceful and slow-moving; does not disturb plants or tankmates

Breeding & Reproduction

• Egg Laying:

  • Will lay tiny white sesame seed-like eggs on glass, rocks, or decor

  • Eggs are not viable in freshwater—requires brackish water for larvae to hatch

• Population Control: No risk of overpopulation in freshwater tanks
