Common name: Spotted flathead
General information
The Crocodile Flathead, scientifically known as Cociella crocodilus, is a unique and fascinating species that adds a touch of the exotic to any marine aquarium. This species is known for its distinctive, flattened head and body, which allows it to blend seamlessly with the sandy or rubble substrates of its natural habitat. The mottled patterns on its body provide excellent camouflage against predators and also make it an intriguing visual addition to the tank.

Care
Cociella crocodilus requires a tank with a sandy bottom or fine substrate to mimic its natural environment. It is a relatively hardy species but does best in a well-established aquarium with stable water conditions. This species is not overly aggressive but may eat smaller fish or invertebrates, so tank mates should be chosen with care. A varied diet of meaty foods such as shrimp, squid, and suitable fish flesh will keep them healthy and thriving.
Reproduction
In the wild, Crocodile Flatheads are oviparous, with females laying eggs that are then fertilized by the male. In the aquarium setting, breeding is rare, but with optimal conditions and a well-matched pair, it is possible to observe spawning behavior. The eggs are typically adhesive and may be attached to substrate or decor within the tank.
Habitat
Cociella crocodilus is found in the Indo-Pacific region, from the Red Sea and East Africa to Samoa, north to the Ryukyu Islands, and south to Australia. It prefers shallow waters, often found at depths ranging from the intertidal zone to about 100 meters. In the aquarium, replicating a similar depth range with appropriate lighting and water flow is beneficial for their well-being.
