Common name: Flamboyant Cuttlefish
Ascarosepion (formerly Metasepia), commonly known as Flamboyant Cuttlefish, is a genus of cuttlefish known for its vibrant colors and unique behavior. These cephalopods are particularly famous for their ability to produce a dazzling display of colors and patterns across their skin, which is used for communication and camouflage. The Flamboyant Cuttlefish is relatively small, with a mantle length of about 8 centimeters, making it suitable for smaller aquariums, provided their specific care requirements are met.
Flamboyant Cuttlefish are found in the tropical waters of the Indo-Pacific, particularly around northern Australia, New Guinea, and the Philippines. They prefer shallow waters and sandy or muddy substrates where they can hunt for their prey, which includes small fish and crustaceans. One of the most fascinating aspects of Metasepia is their unique locomotion; unlike other cuttlefish that swim by undulating their fins, Flamboyant Cuttlefish often "walk" along the sea floor using their arms and fins.
In an aquarium setting, they require a species-specific tank with stable water parameters and plenty of hiding spaces. They are sensitive to changes in water quality and require a diet of live or frozen foods such as shrimp and small fish. Due to their specialized care needs and short lifespan of about one to two years, they are recommended for experienced aquarists.
Scientifically, Metasepia is of interest due to its unique toxin, which is similar to that of the blue-ringed octopus, making it one of the few venomous cuttlefish. This adds an additional layer of intrigue for researchers and hobbyists alike, although it necessitates careful handling in captivity. Overall, the Flamboyant Cuttlefish is a mesmerizing species that offers both visual appeal and scientific interest, making it a unique addition to specialized marine aquariums.
