General Description
The Harlequin sweetlips, scientifically known as Plectorhinchus chaetodonoides, belongs to the Haemulidae family under the genus Plectorhinchus. This species is known for its striking appearance and rapid growth rate, reaching a substantial size of up to 72.0cm.
Aquarium Suitability
Aquarists considering the Harlequin sweetlips for their tanks must be aware of its demanding nature. A significant amount of space, specifically a minimum tank size of 2000 liters, is necessary due to the fish's large size when fully grown. Additionally, providing the correct nutrition can be challenging, impacting the fish's overall health and survival.
Care and Hardiness
The Harlequin sweetlips is categorized as a delicate species, requiring careful attention to thrive in a home aquarium setting. Regular and varied feeding is crucial, as this fish has specific dietary needs that are essential for its well-being. Moreover, due to its docile temperament and preference for hiding places, aquarists should create a suitable environment with ample live rocks for shelter.
Reef Suitability
Reef enthusiasts should exercise caution when considering the Harlequin sweetlips for a reef tank. While labeled as reef safe with caution, this species can pose a threat to small fish, shrimps, bivalves, worms, and snails within the reef community.
Aquarium Setup
A successful aquarium setup for Harlequin sweetlips should include a spacious tank with adequate hiding spots created by live rocks. Maintaining water conditions within the ranges of pH 8.1-8.4, temperature between 22.2-25.6°C, and a specific gravity of 1.020-1.025 is essential for the fish's health and well-being.
Behaviour
Known for its shy and docile nature, the Harlequin sweetlips requires a peaceful tank environment and should not be housed with aggressive tankmates. The species also exhibits a behavior of searching through sand for food, a habit that can lead to cloudiness in the water.
Feeding and Diet
Feeding the Harlequin sweetlips poses a challenge as the species requires a varied diet consisting of fish, larger crustaceans, invertebrates, and smaller crustaceans like krill, mysis, and artemia. To ensure successful acclimation to captive environments, providing live food can increase the chances of the fish adapting and thriving in the tank.
Habitat and Distribution
The Harlequin sweetlips can be found in the Indian Ocean, specifically in the Maldives and Cocos Islands, and extends to the Western Pacific from Sumatra to Fiji. This species inhabits areas with benthic crustaceans, worms, and fish as their primary food sources, reflecting their predatory nature within their natural habitat.
