Borneo Crab Care
Vampire crabs do well in an aquarium with plenty of rocks and pieces of wood for them to climb and sit on. They also like Java moss, in addition to a sandy substrate, and the females will dig down in the moss when having her offspring. They need approximately 50% land mass as they need to be able to get out of the water. The water temperature should remain in the 70s (F.) and they are more active in warmer water. Five or six vampire crabs will fit and reside comfortably in a 10-gallon tank, and they are non-aggressive with each other. They can have shrimp and larger snails as tank mates. Although new to aquariums, they seem are hardy and easy to care for and they are sociable.
Borneo Crab Diet
Borneo crabs are omnivore, but they aren’t very active in their search for food; they will just eat whatever is nearby. They will eat both in and out of the water, and will help keep the tank free of organic matter. In addition to the organic matter, Borneo Crabs will eat most anything. It is a good idea to vary their diet, and they will eat small crickets, brine shrimp and earthworm pieces, in addition to other meats. They will also eat most any kind of dried algae, fish flakes or pellets, and dried or fresh vegetables.
Borneo Crab Molting And Reproducing
Borneo crabs will molt about once a year, and they will dig down in the substrate to molt. The process takes several weeks, and can be done in completely freshwater. Breeding also occurs in freshwater, unlike most crabs. The Borneo Crab does not need to be in water to reproduce. The female crab will carry many large eggs for several weeks. When the eggs hatch, the offspring appear as miniature adults; there is no larval stage.
Borneo Crab Behavior
Borneo crabs are sociable, and get along well with each other. Additional tank mates can include shrimp and larger snails; smaller snails are at risk of being eaten. They aren’t especially active; they tend to find a place where they like to sit and stay there for long periods of time. They have a striking appearance, however, and look great in aquariums.
