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.

Approximate Purchase Size: 1 " to 2 1/2"

Customer Testimonials

Carol Racicot Douglas , MA
This crab is so beautiful, I just love it. Nothing else I have cleans like Sally does. She does not leave a rock until she has cleaned every crevise.
Brendan McGuigan Montrose , NY
This crab is nice while he is small but when he becomes mature, he will hunt and kill peaceful aquarium inhabitants. Dr. Jekyll and Mr Hyde Crab is his nickname. Be very careful when introducing one into your system.
C Mills City Not Selected , LA
Does turn rather aggressive but he's so entertaining. Mine does rather amusing dances against the front glass of the tank at night. We love him dearly, temperment and all. I would recommend them highly if you're looking for lots of personality.
