Common name: De Beaufort's Flathead

Scientific name: Cymbacephalus beauforti (Knapp, 1973)

General Information

De Beaufort's Flathead, scientifically known as Cymbacephalus beauforti, is an intriguing species often sought after by experienced aquarists. This bottom-dwelling fish is notable for its elongated body and distinctive camouflaging ability, allowing it to blend seamlessly with sandy and rocky substrates. Its appearance is characterized by a mottled pattern of browns and grays, making it a master of disguise in its natural habitat.

While not as common in the aquarium trade as some other species, De Beaufort's Flathead is appreciated for its unique appearance and behavior. It is often found in the Indo-Pacific region, particularly in areas with sandy or muddy bottoms where it can lie in wait for prey. Its cryptic coloration and sedentary lifestyle make it a fascinating addition to a specialized marine setup.

Care

De Beaufort's Flathead requires a tank setup that mimics its natural environment, with a sandy substrate and ample hiding spots. This species appreciates a calm environment with minimal disturbances, as it tends to be less active and prefers to remain hidden during the day. Due to its sedentary nature, it can be housed in smaller tanks, but a larger aquarium is recommended to ensure proper water quality and stability.

Diet and Feeding

As a carnivorous species, De Beaufort's Flathead primarily feeds on small fish and invertebrates. In captivity, it should be offered a diet of live or frozen foods such as shrimp, small fish, and other meaty items. Feeding should be done once daily, ensuring that the food reaches the bottom of the tank where the flathead resides.

Behavior and Compatibility

De Beaufort's Flathead is generally peaceful but can be territorial towards conspecifics or similarly sized bottom dwellers. It is best kept with other non-aggressive species that occupy different levels of the aquarium. Due to its predatory nature, it should not be housed with very small fish or invertebrates that it might view as prey.

Health and Common Issues

Maintaining optimal water quality is crucial for the health of De Beaufort's Flathead. Regular monitoring of water parameters and a proper filtration system are essential to prevent stress and disease. This species is relatively hardy but can be susceptible to common marine illnesses if not properly cared for.

Habitat

De Beaufort's Flathead is native to the Indo-Pacific region, where it inhabits sandy and muddy bottoms of coastal waters, lagoons, and coral reefs. It is typically found at depths ranging from shallow waters to around 50 meters. Its preference for camouflaging against the substrate makes it a unique and interesting species for aquarists who appreciate a naturalistic setup.
