Nile Puffer (Niger Form)

The Niger River form of Tetraodon lineatus is collected from the Niger and its tributaries across Mali, Niger, and Nigeria, and displays richer orange-yellow flanks with distinctly bolder, more contrasting dark horizontal stripes compared to Nile-drainage specimens. It is typically reported at a slightly smaller average adult size than true Nile fahaka. The care requirements are broadly identical to all T. lineatus: an enormous aquarium, superb water quality, regular hard-shelled prey, and absolutely no tankmates. The Niger form is occasionally exported through West African collection chains and may be encountered in specialist puffer circles. Its robust temperament and striking markings make it a prized specimen despite the demanding size and aggression requirements.

Water: pH 6.8–7.8, temperature 24–28°C, soft to moderately hard; strong current optional; 30% weekly changes. Tank: 300 L minimum; sand and smooth stone substrate; minimal décor to reduce biting opportunities. Feeding: Large snails, mussels, crayfish, prawns, clam on the half shell; hard prey 3–4 times weekly. Breeding: No captive breeding records; seasonal West African river spawner. Compatibility: Solitary only; extremely aggressive; handles must be done with extreme caution due to beak power.
