Care

Cuttlefish require specialized care and a species-specific tank setup. They need a spacious tank with plenty of room to swim and a sandy substrate to mimic their natural environment. The water quality must be pristine, with stable parameters, and the tank should be equipped with efficient filtration. Cuttlefish are carnivorous and need a diet of live or frozen shrimp, fish, and mollusks.

Reproduction

In captivity, breeding Pharaoh Cuttlefish can be challenging. They are semelparous, meaning they die after a single reproductive event. Males display elaborate courtship behaviors to attract females. After mating, females lay clusters of eggs, which hatch into miniature versions of the adults.

Habitat

The Pharaoh Cuttlefish is found in the Indo-Pacific region, from the Red Sea and East Africa to Japan and Australia. They inhabit coral reefs and sandy bottoms, often near seagrass beds, at depths ranging from shallow waters to about 100 meters.

Geographical distribution includes areas such as the Red Sea, Indian Ocean, and the western Pacific Ocean.
