Purple Vampire Crab Care Guide and Species Overview

The Purple Vampire Crab is a striking and unusual semi terrestrial invertebrate prized for its deep purple coloration and bright contrasting eyes. This small crab is popular among hobbyists who enjoy paludarium and vivarium style setups.

Origin and Background

Purple Vampire Crabs belong to the Geosesarma genus and originate from Southeast Asia. They inhabit humid forest floors near streams and shallow water. Unlike fully aquatic crabs, vampire crabs spend much of their time on land and require both land and water areas to thrive.

Appearance and Size

Adult Purple Vampire Crabs typically reach a body size of about 1 to 1.5 inches. Their shells range from dark purple to violet, often paired with bright yellow or orange eyes. Color intensity can vary depending on diet, environment, and individual genetics.

Temperament and Behavior

Purple Vampire Crabs are generally peaceful but can be territorial, especially males. They are best kept in small groups with one male and multiple females. These crabs are shy and tend to hide during the day, becoming more active in the evening and at night.

Tank Setup and Environment

A paludarium setup is required, with approximately seventy percent land area and thirty percent shallow water. Land areas should be built using soil, sand, or coco fiber and decorated with rocks, wood, and live plants to provide cover.

Freshwater is required, and the water section should be shallow with easy access in and out. High humidity is essential and should be maintained through misting or a tight fitting lid.

Temperature should be kept between 72 and 82 degrees Fahrenheit. The ideal pH range is 6.5 to 7.5. Stable conditions and good airflow help prevent mold and stress.

Diet and Feeding

Purple Vampire Crabs are omnivores and scavengers. Their diet should include sinking pellets, algae wafers, frozen foods, small insects, and vegetable matter. Leaf litter such as Indian almond leaves can also be provided for grazing and shelter.

Tank Mates

These crabs are best kept in species only setups. Fish and shrimp may be eaten, and other crab species can lead to aggression. Small snails may survive but are often hunted.

Why Choose Purple Vampire Crab

The Purple Vampire Crab is an excellent choice for hobbyists looking to create a unique display tank. Their vivid colors, interesting behaviors, and semi terrestrial lifestyle make them a standout species.

Conclusion

With proper housing, high humidity, and a varied diet, Purple Vampire Crabs can thrive and display natural behaviors. They are rewarding pets for aquarists interested in paludariums and invertebrate care.
