The species is commonly referred to as the giant freshwater pufferfish due to its massive size, growing to a length of 67 cm (26 inches). As such, these fish are difficult to adequately house in home
aquaria since they require a very large tank and appropriately scaled
water filtration. Mbu puffers are distinct from other members of the
Tetraodon genus due to their labyrinthine patterns of skin pigmentation, in contrast to mottled or straight-striped patterns such as those seen in
Fahaka pufferfish. These patterns become more pronounced as adults. Like all of its
relatives, the Mbu puffer is capable of inflating itself with water or air when stressed or otherwise frightened. == Diet ==
