Tiger Cowrie
Cypraea tigris
A boldly spotted shell with a living animal most reef keepers never expect.

About
The tiger cowrie (Cypraea tigris) is one of the most recognizable shells in the world, but keeping the living animal is a different experience from owning the empty shell. Found across a broad sweep of the Indo-Pacific, this gastropod lives on the seafloor from shallow reef flats down to about 30 meters, where it grazes on algae and organic material. What surprises many new keepers is the mantle. The soft tissue that extends over the shell when the animal is active, partially or fully covering that famous spotted pattern with a frilly, textured layer that looks nothing like what you'd expect. Pull back the mantle and you get the glossy, cream-to-tan shell with dark brown spots that gives the species its name. Tiger cowries are peaceful and won't bother fish or most other invertebrates, which makes them an appealing addition to a reef or FOWLR setup for keepers who want something genuinely different from the usual livestock. They do need live rock with sufficient algae growth to graze on, so a well-established tank matters more than tank size alone. A reasonable choice for a hobbyist ready to move beyond fish-only keeping.
