General Description
The Bullseye Snakehead, scientifically known as Channa Marulius, is a predatory fish belonging to the family Channidae within the Perciformes order. It is also commonly referred to as the 'giant,' 'great,' 'cobra,' or 'Indian' snakehead. This species is distributed across southern Asia and is recognized for its distinct morphological characteristics, including a large mouth with rows of teeth, absence of gular scales, and specific scale counts on various body parts.
Aquarium Setup
When setting up an aquarium for the Bullseye Snakehead, it is crucial to provide a species-specific environment. The tank should have a minimum capacity of 10,000 liters and include ample floating or overhanging vegetation and branches for surface cover. These fish are pelagic and necessitate ample swimming space. Additionally, a securely-fitted hood is essential to prevent escape, with a gap for access to a layer of humid air above the water surface.
Behaviour
Juvenile and subadult Bullseye Snakeheads exhibit relatively peaceful behavior among themselves. However, as they mature sexually, they tend to become aggressive. Hence, it is advisable to house them in a species-specific aquarium to avoid conflicts with other tank mates.
Feeding and Diet
Being obligate predators, Bullseye Snakeheads primarily feed on smaller fish, amphibians, and terrestrial insects in their natural habitat. In captivity, they readily adapt to various dead food alternatives. Younger specimens can be offered chironomid larvae, small earthworms, and chopped prawns, while adults accept fish flesh, prawns, mussels, and similar items. It is crucial to avoid feeding them mammalian or avian meat and not rely on feeder fish to prevent health issues.
Reproduction & Dimorphism
Specific details regarding the reproduction and dimorphism of Bullseye Snakeheads are not provided in the information available.
Habitat and Distribution
Bullseye Snakeheads are commonly found in larger river channels, inland lakes, canals, and swamps with abundant aquatic vegetation. Their distribution spans regions from Pakistan and India to Southeast Asian countries like Thailand, Laos, and Vietnam. Populations have also been reported in Florida, United States. The species is likely less widespread than current records suggest, awaiting further research for conclusive distribution data.
