Vampire crabs are fascinating creatures to care for and can provide hours of entertainment, but certain requirements must be fulfilled to care for them properly. Most often kept as aquarium decorations but can become engaging and educational hobbies in their own right.
Vampire crabs in their natural environment are scavengers, feeding on dead plant material as well as insects and crustaceans for sustenance. When kept as pets, vampire crabs should be provided a mixture of both meat- and plant-based food sources; since vampire crabs are nocturnal species it is recommended they are fed before bedtime.
An aquarium that accurately replicates their natural environment should be used, with an ideal ratio of 80% land and 20% water. The land portion should feature soft substrate, such as sphagnum moss or coconut coir; live plants suitable for climbing should also be added here, offering shelter and food. Likewise, water should be filtered and maintained at between 71-82 degrees Fahrenheit with a pH level of between 7.5 to 8.0 and an increased dGH between 6-10dGH; an humidifier should also ensures 75% humidity level for optimal conditions in this tank environment.
As any pet, vampire crabs may display aggression towards tank mates or their own kind. This behavior could be driven by competition or feeling threatened. Additionally, they can become susceptible to bacterial infections, fungal issues and parasites; though thanks to being inverts they are less prone to certain common fish diseases such as Ich.
