The Sally Lightfoot Crab is also known as the Nimble Spray, Short, or Urchin Crab. It has a brown body, with orange to yellow rings on the legs. It actually belongs to a family of shore crabs, however, it is less likely than the other genera to go on land. Its carapace is very flat. which allows it to hide in small crevices within rock work.

It prefers a strong current and will require a large aquarium with large amounts of rock work where it can hide and scavenge for detritus. It will also eat algae. When large, it can become aggressive and catch and eat small invertebrates and fish.

If insufficient algae is present, its diet may need to be supplemented with dried seaweed. Meaty items should also be offered.
