Our large Albino Mystery Snails will add bursts of color and also act as a fish tank clearers in your aquarium! These tidy snails consume uneaten fish food and wipe off glass, plants, decorations; plus they clear your substrate to keep it the correct color. These peaceful invertebrates grow large as adults, reaching up to 3 inches in diameter and are safe with any fish, shrimp, or plants. Their albino-white bodies feature unique iridescent markings and their shells are striped with various shades of brown to make these snails living, brilliant underwater fish tank decorations. Compared to other freshwater snails, Mystery Snails are characteristically more active and playful; often scaling aquarium walls, extending their antennae in search of food, and climbing up the aquarium pump to the water line to breathe in oxygen. Because of this, ensure the water line in your aquarium is low enough or keep a tank lid in place so your Mystery Snails cannot escape. We often ship smaller sized (.25 to 1.5 inches) snails so you can enjoy your snail longer and watch it 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 illegal species 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).CARE GUIDELINES:- Temperature: 68° - 84° F (20° - 29° C) - pH: 7.6 - 8.4 - KH: 2 - 15 dKH - Minimum tank size: 2.5 gallons per snail - Average adult size: 2.5 - 3+ inches (5 - 7.6+ cm) - Average purchase size: .25 - 1.5 inches (1.3 - 5 cm)
