The crab is very striking with its red and orange markings. It’s active at night and enjoys feeding on shrimp. I keep it in a 55-gallon tank with no other invertebrates. It’s a unique addition to my aquarium.

Beautiful appearance and surprisingly calm for a predatory species. I’ve noticed it burrows into the sand during the day and comes out at night to hunt. Feeding is easy with shrimp and clams.
