What to know before you buy.
Also known as the Red Tomato Crab, this species has a bright red-to-orange carapace and dark legs. Like Vampire Crabs, they are semi-terrestrial and need a paludarium with more land than water. They are social and best kept in groups with more females than males to minimize territorial disputes.
