Black Mystery Snail

Black Mystery Snail - Deep Black Shell, Effortless Clean-Up Crew

The Black Mystery Snail carries a glossy, deep black shell and body, giving it a sleek, understated look that suits any style of aquascape. Like all Mystery Snails, it's a large, hardy freshwater snail that spends its time steadily grazing algae and debris.

Black Mystery Snails are calm, slow-moving and completely peaceful, making them one of the easiest additions to almost any established aquarium, whether you're after a dedicated clean-up crew member or simply an interesting, low-maintenance pet.

At N8 Aquatics, our fish are carefully raised and conditioned to ensure healthy stock suited to home aquariums.
