Mbu Pufferfish (Tetraodon mbu)

A favourite among experienced aquarists, Pufferfish are lovely to raise, and many consider the puffer to be one of the most appealing species to keep. They are often viewed as having the most dissimilar personalities not only when compared to other species, but even amongst themselves.

These Pufferfish are also seen as a reasonably intelligent species and has been reported that they can even recognise shapes. Puffers have been known to identify their owners and may even beg for food during their feeding time.

Their large, expressive eyes, and a face that always seems to be smiling, make them an adorable pet. They are also an interesting thing to view when they inflate, especially when it comes to the more colourful sub-species. While these are charming fish, they can be challenging to raise. However, for those who enjoy a challenge, this puffer is an ideal choice.

The Mbu pufferfish are known to be usually aggressive and do not live well in community tanks, especially when its not their own species.

They are often found individually in their own tanks, supported by aquarists who already have a lot of experience raising fish.

The Mbu Puffer is usually huge. Their body is greeny-yellow in colour and elongated. They also display mottled brown markings over their head and at the top of the body. Its stomach has a cream to bright yellow colour, and its caudal fin is long and yellow, and their eyes are orange in colour.

Their diet is another problematic aspect for most owners. They require most of their diet to be shelled foods such as snails, muscles, crayfish, and clams. These are all essential foods and giving them these things will help towards keeping their overgrown teeth, also recognised as a beak, trimmed down and to ensure good health.

This Pufferfish has eyes that are quite far apart on their head and may need to line themselves up with food before taking a mouthful. They will need to be fed shelled food five times a week and for the remaining two days, should be given softer foods such as frozen bloodworm, small fish or cocktail shrimps.

Sexual Dimorphism

There are no visible sexual differences between male and female Mbu pufferfish.
