Our large Blue Mystery Snails will add beautiful color to any aquarium, but also serve as effective fish tank cleaners! These colorful snails consume uneaten fish food, biofilm, and other waste, and they clean algae off glass, plants, and aquarium decorations. They also eat hair algae and filter aquarium substrate to keep it the correct color. Mystery Snails grow up to 3 inches in diameter and are safe with any nonaggressive fish, live shrimp, and other aquarium animals, plus they are safe for any live aquarium plant (including giant Marimo Moss Balls, Madagascar lace plant, etc.).

Blue Mystery Snail shells are a gorgeous, tranquil light blue color. Their bodies are a darker blue with breathtaking iridescent markings. Compared to other freshwater snails, Mystery Snails are characteristically more active and can often be found “playing” over an aquarium air stone, extending their antennae in search of food, and climbing up the aquarium pump tubing to the water line to breathe in oxygen. Because of this, ensure the water line in your aquarium is low enough or keep an aquarium lid in place so your Mystery Snails cannot escape.

We often ship smaller sized (.25 to 1.5 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. Mystery Snails are not the same species as Apple Snails and do not grow nearly as large.

Freshwater snails such as these are sensitive to copper, nitrates, etc., so we recommend using an aquarium test kit or aquarium reader and consider buying an ammonia, nitrite, and/or nitrate remover aquarium conditioner.
