Males are brighter than females, whereas females have dark spots on their bodies. Even though it’s a smaller fish however, they require an aquarium that contains at minimum 30 gallons of water.

We recommend the breed to only experienced keepers of puffer fish. MBU pufferfish are unique in design on their bodies which may change with age.

Because they tend towards being more aggressive it is recommended for them to be kept in a tank by only them and without other puffer fish.

Although they seldom exceed two inches in length, they do require an extensive tank as they create a lot waste. We recommend that you have an aquarium that is at least 32 inches in length. A large number of tall, live plants will also be needed.

9. Red-Tailed Dwarf Puffer

The Red-Tailed Dwarf pufferfish are a small species that grows only approximately two inches at its highest. They are fond of slightly acidic waters and aquariums that have plenty of live plants.

Males of this breed tend to be bigger than females and have dark brown bodies, with lighter cream-colored stripes on their lower thighs.

Females of smaller size have a flecked brown appearance, with odd shapes and marks. Females and males both have red eyes and tail fins that are red.

10. South American Puffer

The South American puffer is the few puffer fish species that can be found in large groups within the natural world. But, in Aquariums, this is considered to be one of the tougher fish to manage.

We suggest only experienced enthusiasts buy this breed. And in any case, recommend it in the event of a big tank that is suitable for multiple.

If properly maintained, they will have brilliant black and golden stripes that look stunning against the background vegetation.

The South American Puffer will require an area of at least 47 inches in size. The water needs to be filtered extensively and the dense vegetation will require planting. 
It is also necessary to provide them with a hard-food diet as their teeth are prone to grow too large, and you might have to trim them manually.

11. Target Puffer

Target Pufferfish reach 6 inches and require tanks that are at least 35 inches for them to thrive. A constant, strong filtration system is required and the more water moves around the aquarium the more efficient.

The predators of the Target pufferfish are night-time and can be very active during the night. A moonlight can help you watch your Target puffer hunt.


Puffer fish can be extremely rewarding provided you maintain the right conditions for them to develop. A lot of puffers grow to be very large, and smaller ones can are different from different kinds of fish.

It’s a challenge to build an adequate size tank to clean it properly and it’s a decision that you must make prior to the time since a lot of fish live for longer then five years.

We suggest one of the smaller breeds such as that of the Dwarf Puffer, if you’re unfamiliar with puffer fish, and a properly maintained MBU Puffer is sure to be the center of attention in the aquarium community.
