Vampire crabs are semi-aquatic and need a place to get out of the water in the aquarium. These crabs have brightly colored shells and big yellow eyes. The vampire crab is also a great addition to the terrarium or paludarium tank. In the wild vampire crabs live in the water of large flowers. These crabs are imported from India and have very vivid colors of red, green, or orange. This week we have bright red vampire crabs.
