Mystery Snail

Pomacea bridgesii

Mystery snails are freshwater aquarium snails commonly sold under Pomacea bridgesii or closely related Pomacea names, with rounded shells, long tentacles, and active grazing behavior. They are popular in planted and community tanks because they move visibly, eat soft algae and leftover food, and come in shell colors such as gold, blue, ivory, chestnut, and purple. Unlike many tiny pest snails, they grow large enough to be recognized as individual animals. Their biology includes separate sexes and egg clutches laid above the waterline.

Aquarium care for mystery snails centers on stable freshwater, enough calcium for shell growth, gentle filtration, and tankmates that will not nip tentacles or crush shells. They should not be expected to clean a neglected aquarium on their own, and they need supplemental food when algae is scarce. A secure lid matters because females may leave the water to lay eggs and snails can climb out. Breeders watch clutch size, hatchling survival, shell quality, and color lines. Local restrictions can apply because some apple snails are invasive, so species identity matters.
