A freshwater pufferfish is a great option if you’re searching for freshwater fish with a distinctive appearance for your aquarium. This kind of fish is adorable, fat, and has distinctive black patches on its body.
It has an endearingly odd and comical expression on its face. A pufferfish’s ability to inflate itself when a predator approaches or senses danger allows it to escape being devoured by bigger fish. Tetrodotoxin, the venom of these creatures, is very harmful.

Let’s get started right now!
11 Types of Freshwater Puffer Fish
1. Congo Puffer
The Congo pufferfish, as the name suggests, originates from the continent’s rivers. They may grow up to 6 inches long and spend much time hiding from predators in the sand at the bottom of your tank. Black, scarlet, and sand are only some of the many hues available, and the Congo will change their color to match the environment save for blue. As with other pufferfish, they need a big aquarium and are particularly sensitive to nitrates; thus, the water must be extensively filtered.
2. Dwarf Puffer
Pea pufferfish and Pygmy pufferfish are other names for the Dwarf pufferfish. The smallest pufferfish in the world seldom exceeds an inch and a half in length. The Dwarf Puffer is now listed as vulnerable by the International Union for the Conservation of Nature because of habitat loss.
This breed’s vivid colors and little stature make it a favorite among aquarium keepers. Dwarf fish are simpler to house and care for than many other species since these small freshwater pufferfish need a smaller tank and filtration system.
3. Fahaka Puffer
When fully mature, the Fahaka Pufferfish, one of the largest pufferfish varieties, may reach a length of 16 inches. Only seasoned fish keepers should attempt to acquire one of these aggressive varieties. You’ll need a tank that’s at least 60 inches long, as well as a lot of vegetation to cover the surface. While eating, these fish are known to target your fingers and inflict a nasty bite.

4. Golden Puffer
Both a bright and a dark variant of the Golden Puffer are available. The pufferfish is a light form and has a white body with yellow spots. Yellow spots dot a black torso in the dark version of the illustration. They have spherical bodies with little fins that are positioned far back on their bodies. On their skin, there are microscopic toothlike projections that look like sandpaper. These projections become more apparent as they puff out. When fully developed, certain fish may grow to about 20 inches in length.
5. Imitator Puffer
Known as the Dwarf Malabar Puffer or Imitator puffer, this little pufferfish is another form of pufferfish. Yellow is the primary color of this fish’s body. Compared to females, males have a more vibrant coloration, while females have black patches on their bodies all throughout. However, even though they are tiny fish, they need at least 30 gallons of water in an aquarium to thrive.
6. MBU Puffer
MBU Pufferfish are a huge pufferfish species that may grow to 26 inches in length. It’s tough to maintain these fish healthy in an aquarium due to the size and filtration requirements. It is thus recommended for experienced pufferfish owners only. The pattern on the body of MBU pufferfish may alter as they mature.
7. Ocellated Puffer
One of the rarest pufferfish breeds is the Ocellated pufferfish. This strain of fish was developed in captivity and is now found in rivers and streams across South Asia. Individual fish of this breed have distinct personalities, and the males will do all in their power to protect their eggs. More so than many other species, they like to be maintained in pairs and are known for their calm disposition. They may also be kept in a smaller aquarium than most, with a normal volume of just 20 gallons required. In spite of this, you’ll still need to install a powerful filtration system.
8. Red-Eyed Puffer
Four distinct species of pufferfish collectively known as the Red-Eyed Puffer share red-eye. This particular kind of pufferfish is notorious for being more aggressive and more difficult to keep in captivity. Because of their aggressive nature, it’s recommended to keep these pufferfish alone in an aquarium. Even though they seldom grow above a length of 2 inches, they need a huge tank to accommodate their waste production. At least 32 inches in length is recommended. Plants of various heights will also be necessary.
9. Red-Tailed Dwarf Puffer
The Red-Tailed Dwarf pufferfish is a little species with a maximum length of just two inches. These fish like slightly acidic water and a lot of living flora in their aquariums. Men of this breed are bigger than women and have dark brown bodies with light cream-colored stripes on the bottom half of their bodies. The smaller females are dark and speckled, with a variety of forms and patterns on their bodies. They feature red eyes and red tail fins, which are distinct between males and females.

10. South American Puffer
Only a few pufferfish species live in groups in the wild, and the South American Puffer is one of them. But in the aquarium, it’s one of the most challenging fish to keep alive and well. Even if you have a big enough tank, we don’t advocate purchasing this breed unless you’re an experienced fisherman. They have striking golden and black stripes that contrast well with the surrounding foliage when they are properly cared for. Forty-seven inches is the minimum length of tank required for the South American Puffer. Filtering the water and establishing thick vegetation will be necessary. Because their teeth are prone to overgrowth, you will also need to provide them with hard food.
11. Target Puffer
Target Pufferfish may grow up to 6 inches long and need a tank that is at least 35 inches long to be happy. An aquarium’s filtration system must be robust and constant, and the more water it circulates around, the better. As nocturnal creatures, target pufferfish are quite active at night. Watching your Target puffer hunt at night is a wonderful experience.
If you’re able to provide them with the right conditions, pufferfish may be a great investment. It is possible to find pufferfish of all sizes, and even the smallest have personalities that are distinct from those of other species. Many of these species are long-lived, so you’ll need to make a long-term investment in a big tank and proper filtering before you get started. For newcomers to pufferfish, we suggest the Dwarf Puffer, while a well-cared-for MBU Puffer will be the talk of the aquarium world.
