🦀 Rainbow Vampire Crab (Geosesarma rouxi “Red-Legged”) – Neon Highlights of the Paludarium

SIZE: 1 – 1.5 inches (adult size)

Add a burst of neon color to your paludarium with the Rainbow Vampire Crab, a brilliantly patterned Geosesarma species prized for its glowing eyes and vivid red legs. With their striking mix of purple, orange, yellow, and crimson tones, Rainbow Vampire Crabs look like living jewels—tiny splashes of color exploring rock, wood, and moss.

The Rainbow Vampire Crab (Geosesarma rouxi “Red-Legged”) features a compact, rounded carapace with purple-to-violet body tones, bright yellow eyes, orange highlights, and signature red legs that give this morph its name. As semi-terrestrial crabs, they spend most of their time on land while using shallow freshwater pools to hydrate, feed, and molt. Curious and bold yet generally peaceful in small groups, they are perfect centerpiece invertebrates for paludariums and land–water aquascapes.

Our Rainbow Vampire Crabs are healthy, well-established, and acclimated to captive conditions. With proper humidity, clean water, and multiple hides, they are surprisingly easy to keep—even for hobbyists new to Geosesarma species. Their omnivorous scavenging behavior helps keep the enclosure tidy by consuming leftover food and detritus on both land and in shallow water zones.

🦀 Why Choose Rainbow Vampire Crabs?

Unmatched Color & Contrast:
Purple carapace, glowing yellow eyes, and vivid red legs create a striking rainbow look.

Active & Fun to Watch:
See them climb, explore, and interact—particularly lively during evening and night hours.

Perfect for Paludariums:
Ideal for mixed land–water environments with moss, wood, and shallow pools.

Helpful Scavengers:
They eat leftover food and biofilm, contributing to a cleaner habitat.

Hardy & Beginner-Friendly:
With stable humidity and hides, Rainbow Vampire Crabs adapt well and thrive in captivity.

Provide cork bark, stone caves, leaf litter, and dense plants to create secure hiding and molting areas. Because these crabs are clever climbers and escape artists, a tight-fitting lid is essential. Avoid keeping them with fish or fully aquatic species—best housed in species-only paludariums or with carefully selected invertebrates that share similar environmental needs.
