Planning your aquarium

The library starting point is 20+ 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

Unlike small ramshorns, this large species may eat healthy aquarium plants.

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: Vegetables, Sinking wafers, Aquatic plants.

Offer supplemental foods when the tank does not provide enough natural grazing. Remove uneaten food before it fouls the water.

Compatibility

The current rule-based checker does not list a dedicated pairing warning for this species. That does not mean every pairing is safe; review temperament, adult size, diet, habitat and water requirements.
