General Description
The Harlequin hind (Cephalopholis polleni), also known as Harlequin cod or Harlequin grouper, belongs to the Serranidae family. It is a species found in the East Indian Ocean, Australia, Indonesia, and the Central/West Pacific regions. This colorful fish can grow up to 43.0cm in length and is recognized for its striking appearance.
Aquarium Suitability
The Harlequin hind is considered suitable for special aquarium setups. However, it demands a very large aquarium when fully grown, which can pose a challenge for home aquarium enthusiasts. Due to its rapid growth rate, it requires ample space to thrive.
Demands, Care and Hardiness
Regarded as hardy, this species can be aggressive towards similar fish if not provided with sufficient space. It requires a varied diet comprising fish, larger crustaceans like shrimp and crabs, as well as smaller crustaceans such as krill and mysis. Providing adequate hiding places, such as live rocks, is crucial for their well-being.
Reef Suitability
The Harlequin hind is considered reef safe with caution, meaning it can coexist with reef inhabitants but may display aggression towards other species. Careful consideration should be taken when introducing it to a reef environment.
Aquarium Setup
Creating an environment that mimics the deep-sea conditions of the Harlequin hind is crucial for its well-being. Dim lighting is recommended to simulate its natural habitat. A large aquarium with hiding spots is essential, along with a robust filtration system to manage its heavy feeding habits.
Behaviour
Initially shy when introduced to a new aquarium, the Harlequin hind can become more aggressive, especially if not provided with ample space. This species is known for its voracious appetite and may consume various fish, shrimps, crabs, and other suitable-sized prey.
Feeding and Diet
To ensure the health of the Harlequin hind, a varied diet is necessary. Feeding them fish, larger crustaceans, and smaller crustaceans like krill and artemia will help meet their nutritional needs.
Habitat and Distribution
The Harlequin hind is primarily found in the Indo-Pacific region, ranging from scattered insular locations from the Comoros to the Line Islands. It is notably absent from areas such as the Red Sea, East African coast, Sri Lanka, Australia, New Guinea, and larger Indonesian islands. This species thrives in deep-sea habitats and requires specialized care to replicate its natural environment.
