The Palembang Puffer (Pao palembangensis), formerly known as Tetraodon palembangensis, is a striking, predatory freshwater puffer with bold patterning and a demanding care profile. Native to rivers and floodplain habitats across Southeast Asia, this aggressive species requires specialist-only care and is best kept alone. Available for sale UK-wide, the Palembang Puffer is an excellent choice for experienced aquarists seeking a charismatic, intelligent fish with expert-level care requirements.
Pao palembangensis displays a robust, rounded body with intricate patterning of dark brown to black markings on a yellow to golden background. The species is often called the "Humpback Puffer" or "Dragon Puffer" due to its prominent dorsal hump and elaborate markings. The large, expressive eyes and beak-like mouth create a distinctive, intelligent profile. Coloration intensifies in well-conditioned individuals and can vary based on mood and environment.
The Palembang Puffer inhabits freshwater rivers and floodplain habitats across Thailand, Laos, Malaysia, and Indonesia. These environments feature moderate to strong current, abundant submerged wood, and areas with rocky or sandy substrates. The fish are solitary predators, hunting for snails, crustaceans, and other invertebrates while sheltering among roots and wood.
A minimum 500-litre aquarium is essential for the Palembang Puffer, with larger tanks preferred for adult specimens. Provide ample hiding places using driftwood, caves, smooth rocks, and PVC pipes. Avoid sharp décor, as puffers can be clumsy swimmers. Strong filtration and excellent oxygenation are critical, as this species is messy and produces substantial waste. A secure lid is essential, as puffers can jump.
Maintain neutral to slightly acidic water with pH 6.5-7.5 and temperatures between 24-28°C. General hardness (GH) of 5-12 dGH is ideal. The Palembang Puffer is adaptable but performs best in well-oxygenated water with strong circulation. Perform weekly water changes of 30-40% to control nitrate and maintain stable parameters. Avoid poor water quality or unstable chemistry.
Pao palembangensis is a carnivore that requires a varied diet of meaty foods. Offer snails, crustaceans, worms, insect larvae, and other protein-rich frozen or live foods. Hard-shelled prey such as ramshorn snails, Malaysian trumpet snails, or crayfish are essential to help wear down the puffer's ever-growing teeth. Feed once daily or every other day in portions that are consumed within a few minutes.
This species' teeth grow continuously and must be managed with a diet that includes hard-shelled foods. Monitor tooth growth and consult a vet if trimming becomes necessary.
The Palembang Puffer is a highly intelligent, aggressive, and solitary fish. This species is highly predatory and will bite tankmates, making it unsuitable for community tanks. Puffers are curious and interactive, often recognizing their owners and begging for food. They are also skilled at rearranging tank décor and can be destructive.
Best kept alone. Avoid small fish, slow-moving fish, fin-nipping species, other puffers, and shrimp. This species is not suitable for community aquariums and should be housed singly in a species-only setup.
Breeding is uncommon in home aquaria, and reliable captive spawning information is limited. If breeding occurs, a large, carefully conditioned pair and excellent water quality are typically required. Little is known about parental care or fry rearing in captivity.
