Neritina natalensis

Hire one of these patterned grazers and the algae film on your glass simply stops existing — with zero risk of a snail plague.

Difficulty

easy

Care tips

• One snail per 20 L keeps grazing sustainable
• Keep 22-26 °C in hard, alkaline water for shell health
• Eggs appear but never hatch in freshwater — no overrun
• Offer algae wafers if the glass gets too clean
• Keep the lid closed; they wander above the waterline
