General Description
The Channa Pleuropthalma, commonly known as the Ocellated Snakehead, is a species under the Channidae family. It is characterized by its ocellated spots present on the flanks, leading to alternate names such as the 'orange-spotted snakehead.' Possessing a unique respiratory adaptation, it has suprabranchial chambers that allow it to breathe atmospheric air, aiding in survival in hypoxic conditions or even out of the water for extended periods.
Aquarium Setup
The Ocellated Snakehead requires a species-specific aquarium setup with at least 860 liters of water capacity. Unlike most Channa species, it is pelagic and needs ample space to swim. Providing surface cover like floating or overhanging vegetation is advised. C. pleurophthalma is known for its escape artist skills, so a tightly-fitting hood with a gap for access to humid air above the water surface is essential. Young individuals are sensitive to water changes and do not need frequent maintenance.
Behaviour
This species is one of the few snakeheads that form aggregations during their lifetime. While generally shy, they can turn bold and aggressive towards tankmates, especially when kept in a conspecific group. Small fish that can be seen as prey may be harmed or consumed by the Ocellated Snakehead.
Feeding and Diet
Being an obligate predator, C. pleurophthalma primarily feeds on smaller fish, amphibians, and terrestrial insects in the wild. In captivity, they adapt well to dead food alternatives. Feeding young snakeheads chironomid larvae, small earthworms, and chopped prawns is recommended, while adults accept fish flesh strips, whole prawns, and mussels. It's crucial to avoid mammalian or avian meat and feeder fish to prevent health issues.
Reproduction & Dimorphism
Reproduction details of the Ocellated Snakehead remain unrecorded, but in their natural habitat, they form temporary pairs during breeding, leaving the main group to spawn in marginal vegetation. This species shows sexual dimorphism through the slender build of males compared to females, with males developing a bluish coloration while females appear greenish.
Habitat and Distribution
Native to southeastern Sumatra, as well as the Kapuas and Barito river basins in Kalimantan, Indonesian Borneo, the Ocellated Snakehead thrives in streams and mangroves. The type locality for this species is Bandjarmasin, Borneo, Indonesia.
