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.[2] 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
It feeds on smaller fish, mollusks, crustaceans, snails, worms, and crayfish. Species kept in captivity require a varied diet consisting of shelled foods to help ensure good health and to prevent tooth overgrowth.
