Mystery Snail

Planning your aquarium

The library starting point is 10+ 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

Large colorful freshwater snail that benefits from calcium-rich water.

Allow enough open surface access for breathing and keep water suitably mineralized for shell health.

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: Snail pellets, Algae wafers, Blanched vegetables.

Supplement natural grazing with snail foods and vegetable matter; remove excess promptly.

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 Assassin Snail: Assassin snails may attack other snails; large healthy mystery snails are less vulnerable but the risk remains.

These are selected rule-based cautions, not a complete compatibility assessment.
