Parachanna obscura
An African snakehead ranging from West Africa to the Nile and Congo basins, brown with dark blotches. A predator approaching 50 cm, it depends on breathing air at the surface.
Parachanna obscura is sold in Japan as 'Channa obscura'. Once known as Channa obscurus, it belongs to Parachanna, a genus of snakeheads found only in Africa and separate from the Asian Channa. It is widespread from the Senegal River to the Chad system, including the Volta, Niger and many coastal West African basins, as well as the Nile and Congo basins (FishBase). FishBase records up to 50 cm SL and 1 kg. It lives among marginal vegetation and on floodplains, feeding on insects and small fish, and is an obligate air-breather that drowns without surface access. Captive breeding is rare: some report pairs spawning in an embrace among floating plants with both parents guarding the eggs, others report cave spawning. It treats fish smaller than two-thirds of its size as food, so it is best kept alone. Juveniles are sold by Japanese specialist shops; consider the adult size before buying.

Temperature
26〜28℃
Carnivore (fish, prawns, bloodworm, mussels)
26-28°C (FishBase); Seriously Fish gives 26-30°C, pH 6.0-7.5 and hardness 5-20, and notes it is strictly tropical.
Adults exceed 40 cm, so lifelong care needs a large tank with ample length and depth. Cover part of the surface with floating plants, leave open swimming space, and use a gap-free lid with an air layer.
Eats fish smaller than about two-thirds of its size. It has been kept with similarly large, robust fish such as bichirs and big catfish, but this is not safe; keeping it alone is best.
Carnivorous and fond of live food, but adapts well to frozen prawns, bloodworm and mussels; it usually refuses dried foods.
Rarely bred. Pairs may form among grown-on juveniles, but the others may then be killed.
It drowns without surface access. Guard against jumping and escape, and never release it.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The ideal temperature for African obscure snakehead is 26〜28℃. Avoid sudden temperature changes and maintain a stable environment.
African obscure snakehead typically reaches Up to 50 cm SL and 1 kg recorded (FishBase) as an adult. Size may vary depending on care conditions and individual genetics.
African obscure snakehead feeds on: Carnivore (fish, prawns, bloodworm, mussels). Aim for a balanced diet with appropriate feeding frequency.
