Orchid Vampire Crab

Orchid Vampire Crab (Geosesarma sp. “Orchid”) — A Rare and Ethereal Jewel of the Terrarium

The Orchid Vampire Crab (Geosesarma sp. “Orchid”) is one of the most rare and visually stunning members of the Vampire Crab family. With its delicate, soft lavender-to-orchid body colouration, vivid yellow eyes, and intricate shell patterning, this small semi-terrestrial crab is a living work of art — a species that commands attention and admiration in any paludarium or terrarium setup. Rare in the trade and highly sought after by collectors, the Orchid Vampire Crab is a true prize for the dedicated enthusiast.

Ethereal Beauty, Captivating Behaviour

Like all Vampire Crabs, the Orchid variety is semi-terrestrial — spending much of its time on land while requiring access to water for moulting and hydration. Its soft orchid and lavender colouration is unlike any other freshwater crab in the hobby, creating an almost otherworldly appearance that is particularly striking under warm or UV lighting. Active, curious, and surprisingly bold, Orchid Vampire Crabs are fascinating to observe as they explore their environment, forage for food, and interact with one another.

Paludarium Compatibility

The Orchid Vampire Crab thrives in a well-planted paludarium with tropical plants such as pothos, bromeliads, mosses, and ferns that provide cover, climbing opportunities, and humidity retention. It can be kept in small groups with careful attention to sex ratios — one male to two or more females is recommended. Avoid housing with fish or invertebrates in the water section that may be predated upon.

Rare, ethereal, and endlessly captivating — the Orchid Vampire Crab is the paludarium jewel that transforms any setup into a living work of art.
