The Common Marble Shrimp, also known as the Saron Shrimp, was first documented in 1811. During the daytime, it displays a brown body with green spots that may have white speckling. Its legs have alternating dark brown and white speckled bands on a brown background. Males possess feathery appendages on their back and elongated first pair of walking legs. This species is nocturnal, and its body turns primarily red at night, allowing it to blend into the shadows of the twilight. When introduced to an aquarium, the Saron Shrimp requires a dark hiding place. After acclimation, it will become active during the day and usually inhabit the coral rubble at the base of the reef. Saron Shrimp are sensitive to high nitrates or copper and require the proper level of iodine in the water for molting. A Saron Shrimp’s diet may consist of plankton, brine shrimp, flaked food, frozen food, and small pieces of fish.
