- The aquarium contains shrimp-eating fish
- The tank is newly cycled
- Water conditions change frequently
A striped African nerite widely kept as an algae-grazing aquarium snail.
Appearance and Identification
Rounded shell with contrasting dark and yellow, gold, or olive stripes; pattern varies between individuals.
The aquarium name Zebra Nerite is applied broadly. This record uses Vittina natalensis, with Neritina natalensis retained as a previous scientific combination.
External sex differences are subtle or unreliable without species-specific examination.

Provide stable water, mineral availability for shell growth, secure décor, and enough natural grazing surface.
Behaviour and Tankmates
Peaceful freshwater snail that spends much of its time grazing or searching for food.
Usually non-territorial and may be kept singly or with compatible conspecifics when food and space are adequate.
Not normally territorial.
Suitable with peaceful tankmates that do not nip, crush, or prey on snails.
Water Parameters
Use alkaline, mineral-rich water and provide established algae or biofilm. Freshwater supports adults, but larvae normally require brackish conditions.
Parameter caveat
Stable conditions are more important than chasing exact numbers.
Feeding
- Diet types
- Algae Grazer, Aufwuchs Grazer, Detritivore
- Feeding frequency
- Daily
- Preferred foods
- Mature biofilmPrimary natural grazing resource.
- Algae-based sinking foodSupplement when natural growth is insufficient.
- Softened vegetables or complete snail foodFeed in small amounts and remove leftovers.
Specialized algae and biofilm grazer. Provide a mature aquarium with natural growth and supplement carefully when grazing becomes scarce.
Do not place in a newly established aquarium without sufficient algae and biofilm.

- Incubation
- 28 days
- Parental care
- None
- Baby foods
- Mature biofilm and fine natural foodsProvide stable grazing surfaces suitable for juveniles or hatchlings.
Egg capsules may be deposited in freshwater, but the free-swimming larvae normally require brackish or marine conditions for development.
