no. its more of a pure light purle crab. I came home and found them dead. I thought the sand was a little dried out so it took 2-3 cups of aquarium water out of my fw tanks poured it in,then sprincled instent ocean of the sand. I sould have leaft them alone. I still want to know what they are. pretty coll little guys.
