Mbu Pufferfish – Tetradon mbu
This species of pufferfish can reach 26 inches and can weigh up to 15 lbs. When it puffs up to escape predators or to show that it's scared, this puffer can reach the size of a football. This act of puffing is done by swallowing air or water to fill up the stomach, thus causing the animal to swell. They are found in Central Africa. All pufferfish whether they are freshwater or saltwater are all carnivorous. They feed on smaller fish, mollusks, and crustaceans. In captivity they need snails or shelled shellfish to help wear down their fused teeth. By the way, pufferfish have 4 fused teeth in each jaw. Mbu pufferfish are also very aggressive and will not think twice about taking chunks out of any fish that share their tank. Some puffers are highly poisonous. They contain the same toxin that blue-ringed octopus produce, tetrotoxin or tetrodoxin. It's important to note that there are no known anti-toxins for this toxin. Unless you can care for this animal do not purchase this animal. We have too many unwanted pets as it is.
