Purple Mystery Snail (Medium) (Pomacea diffusa)

Add a splash of rich color and natural elegance to your freshwater aquarium with the Purple Mystery Snail (Pomacea diffusa). Admired for its beautiful shell that ranges from soft lavender to deep purple hues, this peaceful freshwater invertebrate is both a stunning ornamental addition and a valuable member of your aquarium's clean-up crew.

Our Medium-size Purple Mystery Snails are healthy, active, and approximately 1–1.25 inches (2.5–3.2 cm) in shell diameter, about the size of a large grape. At this stage, they are well established, adapt quickly to new aquariums, and still have room to grow into impressive adults.

Purple Mystery Snails spend their day grazing on algae, biofilm, and uneaten food, helping to maintain a cleaner aquarium while adding constant movement and interest to your underwater world. Their peaceful temperament makes them an excellent choice for community aquariums, where they coexist beautifully with tropical fish, shrimp, and other non-aggressive invertebrates.

For optimal health and shell development, provide clean, stable water with adequate calcium and a varied diet that includes algae wafers, sinking pellets, blanched vegetables, and other quality invertebrate foods.

Whether you're creating a colorful planted aquarium or looking for a unique invertebrate to complement your aquascape, the Purple Mystery Snail offers beauty, utility, and easy care for aquarists of every experience level.
