The Congo puffer or potato puffer is a freshwater pufferfish found in areas of the Congo River in Africa, including rapids.
The T.miurus populations in the wild are still healthy in suitable habitats and it is considered 'Least Concern' by the IUCN
Tetraodon miurus can grow to an approximate length of 15 cm.
They are inactive fishes, spending most of their time buried in sand or other substrate, with the ability to adapt their colouration to hide from potential prey. However, many colour variations are seen within the species, ranging from black to sandy to bright red. It will not change to blue, though, but if in a dark substrate will generally become darker in color.
