B-Grade Black Mystery Snail shells may have minor damage or calcification, but are otherwise perfectly healthy. Black Mystery Snails have shells that range from black to dark purple, although black snails are the most common. Some are black with tan striping, while others are dark purple with gray striping, and black snails with purple stripes are the most rare.
Â
Black Mystery Snails add decorative color contrast to your aquarium and are effective as fish tank cleaners! Mystery Snails reduce the need for a UV aquarium sterilizer because they consume uneaten fish food and other waste, clean algae off glass, plants, decorations, and substrate. This peaceful invertebrate grows large as an adult, reaching up to 3 inches in diameter, and is safe with any nonaggressive fish, dwarf shrimp, or plants.
Â
Compared to other freshwater snails, Mystery Snails are characteristically more active and can often be found “playing†over an aquarium bubbler, extending their antennae in search of food, and climbing up to the water line to breathe. Because of this, ensure the water line in your aquarium is low enough or keep a tank hood or mesh aquarium lid in place so your snails cannot escape. Â
Â
We often ship smaller sized (1/2 to 1-1/2 inches) snails so you can enjoy them longer and watch them grow. A young Mystery Snail can double in size over the course of two weeks to months.

NOTE: Contrary to what some websites state, Mystery Snails are NOT the same species as Apple Snails. Apple Snails are an invasive species and illegal to own in the United States. Our Mystery Snails do not grow to the tremendous size that Apple Snails do (often as big as an apple).
