This Fish, Found In Africa's Congo, Can Change The Colour Of Its Skin

Water bodies worldwide host a diverse array of fascinating fish species, from rainbow fish to barbs, each exhibiting unique behaviours and adaptations. Among these captivating aquatic creatures is the Congo Pufferfish, also known as the Potato Pufferfish, distinguished by its chameleon-like colour-changing ability — a defence mechanism against predators. A Twitter user recently shared a video showcasing the extraordinary behaviour of this creature, emphasising its remarkable ability to crawl backwards.

In the video, the Congo Pufferfish is observed flapping its wings rapidly while moving backwards before executing a skilful upside-down turn. Subsequently, the pufferfish buries its head in the sand, propelling itself forward with surprising speed while exhibiting intricate body wriggles. Once fully submerged in the sand, only its eyes remain visible, offering a close-up view. The caption affectionately introduces the creature as ‘Tater the potato Puffer,’ also acknowledging its alternative name, the Congo Puffer.

According to information from the Aquariadise website, the Congo Puffer is a freshwater fish native to the Congo River in the Democratic Republic of the Congo. Scientifically named Tetraodon Miurus, this pufferfish can reach sizes of up to 6 inches (15.2 cm). Notably, it possesses the potent Tetrodotoxin neurotoxin, primarily found in its liver and sex organs, posing a threat to predators and potential human consumers. However, the toxin is only dangerous when ingested.

Several unique features characterize the behaviour and biology of the Congo Pufferfish:

Inflatable Defense Mechanism: To deter predators, the Congo Pufferfish can inflate its stomach like a balloon with air or water, creating a larger, less appealing target.

Ambush Predation: These fish display a strategic hunting technique by burying themselves in the sand, lying in wait for extended periods to ambush prey.

Sedentary Lifestyle: The Congo Pufferfish tends to remain inactive and submerged in the sand for a significant portion of its time, contributing to its stealthy hunting approach.

Carnivorous Nature: Congo Pufferfish are carnivores and should be housed separately in aquariums. Their predatory tendencies extend to devouring smaller fish and causing harm to larger ones by cutting their fins.

The Congo Pufferfish stands out not only for its captivating colour-changing ability but also for its intriguing behaviours and adaptations that contribute to its survival in the aquatic environment.
