If you’re looking to venture into keeping crabs as pets, the Red Devil Vampire Crab, scientifically known as Geosesarma hagen, is a real head-turner, and can be kept with other vampire crab morphs. Hailing from the forest streams of Java in Indonesia, these small but colorful crabs come with a dark body and dramatic red or orange claws. If you think their name is exciting, just wait till you see them in action in your own setup. You’ll want to prepare a paludarium for these little critters, which is a habitat with both water and land areas. This is important because these crabs are semi-terrestrial, meaning they like to switch between taking a dip and strolling on dry land. These crabs are not huge, around 2 inches in size, but what they lack in size, they more than make up for in personality and looks. Red Devil Vampire Crabs aren’t picky eaters. You can feed them insect-based foods, a bit of fish food, and they’ll even munch on some greens. Just keep their environment clean, and maintain stable humidity and temperature, and you’re good to go.
