Olive Nerite Snail
Peaceful algae grazer; eggs laid in freshwater usually do not develop there.
Planning your aquarium
The library starting point is 5+ US gallons. Check adult size, grazing surface, oxygenation, and food supply.
Stable water and adequate dissolved minerals help protect shell growth. Do not assume that every snail eats the same foods or that an aquarium has enough natural algae.
Behavior and tankmates
Peaceful algae grazer; eggs laid in freshwater usually do not develop there.
Check tankmates for snail-eating behavior, and keep medication ingredients in mind. Some snails reproduce readily, while others require specialized breeding conditions.
Food and feeding
Food options: Natural algae, Biofilm, Algae wafers.
Offer supplemental foods when the tank does not provide enough natural grazing. Remove uneaten food before it fouls the water.
Tankmate cautions in the checker
- Use caution with Pea Puffer: Puffers may bite snails; nerite size does not guarantee safety.
These are selected rule-based cautions, not a complete compatibility assessment.
