PLEASE NOTE: This species is a semi-terrestrial crab. Its habitat must be at least half (and preferably more) land with freshwater. It is an ideal paludarium animal.

 

The Red Arm Vampire Crab is a fascinating semi-terrestrial species that is beautifully marked. It is communal with its own species and is an excellent choice for the paludarium, even nano-sized enclosures!

 

The Red Arm Vampire Crab (Geosesarma bicolor) is a small, very colorful, semi-terrestrial species that is native to Java, Indonesia. It inhabits forest areas near streams, rivers, and ponds. It spends most of its time on land, but also often submerges in freshwater, including when it molts. It is communal with its own species, and males typically are larger than females, and also have much larger claws. 

 

In nature, the Red Arm Vampire Crab lives in leaf litter and vegetation. In the paludarium, it requires ample land area. It typically will not eat healthy plants, but it will often help keep them clean and it may consume dead leaves. Like most crabs, it needs plenty of cover, especially when molting, so lots of decor is necessary. While it is communal with its own species, it is often aggressive with other types of crabs, including other vampire crab species with which it competes in the wild. It is a skilled climber, so extra care must be taken to ensure that it does not escape its enclosure.

 

Like most crabs, the Red Arm Vampire Crab is an omnivorous scavenger and an opportunistic hunter on occasion. It feeds on filamentous algae and detritus in the paludarium and will also readily accept high-quality dry foods that are rich in plant matter. Fresh and dried vegetables are also excellent food sources, as are insects, worms, and other invertebrates. Due to its opportunistic nature, the Red Arm Vampire Crab might eat other ornamental invertebrates and fish, so its tankmates must be chosen with great care.

   

*IMPORTANT* Please "Choose a Variant" above before adding this crab to your cart. We offer a "B-Grade" variant for these crabs. Our “B-Grade” crabs are simply specimens that are missing legs or claws unless otherwise stated. Loss of appendages is not permanent and happens commonly with crustaceans.  They are completely healthy with excellent coloration and will completely regenerate lost appendages within 1 to 2 molts.
