Marbled Coral Cat Shark-SM Atelomycterus marmoratus

Atelomycterus marmoratus—known as the Coral Cat Shark or Marbled Catshark—is a striking, bottom-dwelling species prized for its bold speckled pattern and calm, deliberate movements. This nocturnal shark prefers wide open floor space, gentle flow, and shaded retreats to rest during the day. Provide a soft, fine sand bed (no sharp gravel), stable salinity, strong oxygenation, and a securely covered aquarium. Juveniles thrive in very large marine systems and can reach over 24", so plan for a long-footprint tank (we recommend 300+ gallons) with rockwork arranged to maximize swimming lanes. Feed a varied meaty diet—shrimp, squid, clam, silversides, and quality marine carnivore preparations—using tongs for target feeding. Best housed with peaceful, sizable tankmates; avoid small fish, ornamental crustaceans, or delicate corals it could disturb while foraging.
