Do Puffer Fish Live In Freshwater?
Pufferfish are found in the Atlantic, Pacific, and Indian Oceans. Some even swim up to the places where salty sea water meets the river waters and live in these brackish waters.
Some species swim up to the rivers and live in freshwater. So, the answer to the question: do puffer fish live in freshwater is yes. There are many varieties of pufferfish that only live in freshwater.
These varieties are mainly found in the tropics and subtropics, so you’d find freshwater pufferfish in the rivers of South America, Africa, and South Asia.
Where Do Puffer Fish Live?
Pufferfish have varied habitats. Mostly, they prefer shallow water or water that is not too deep. You might find them in coral reefs and rocks at the bottom of the sea. The coral reefs are abundant with pufferfish because they find plenty of food in them.
Adult puffer fish are more likely to be found near the land than out in the open sea. Mostly, they prefer clear water although some species thrive in muddy waters.
As mentioned before, there are freshwater pufferfish species too. It is estimated that out of almost 120 varieties of pufferfish, 30 varieties spend their entire lifecycle in freshwater, while the remaining are found in estuarine and inshore waters.
You might even find some living midway in brackish waters where rivers meet the sea. Some species even travel back and forth between different environments.
One thing is clear about pufferfish: they do not like cool water and prefer warmer temperatures. Resultantly, they are mostly found in the tropics, present in moderate numbers in the temperate waters, and not at all in the cold, frigid zones.
12 Popular Freshwater Puffer Fish Types
There are several varieties of pufferfish available all over the world. The freshwater varieties are popular among aquarium hobbyists as they are slightly easier to keep.
Some of the common ones are Mbu Pufferfish, Fahaka Pufferfish, Red-Eyed Red Bellied Pufferfish, Dwarf pufferfish, etc. These are kept by aquarium hobbyists.

|Ocellated Puffer||None||Rivers in Asia||Greenish golden color with lighter bellies||Very aggressive||Best housed alone.|
Are Freshwater Puffer Fish Poisonous?
Yes. Many varieties of freshwater pufferfish are toxic or poisonous if consumed. For example, Saxitoxin in freshwater pufferfish in Thailand was known to cause severe food poisoning symptoms in people who ate it at a restaurant.
Not all varieties of pufferfish are poisonous though. It is also important to note that the toxin is produced in the pufferfish’s organs due to the diet it eats in the wild. In captivity, if your freshwater pufferfish does not get this specific and varied diet, so the chances are that it is not able to produce tetrodotoxin at all.
However, it is safe to assume that almost all freshwater pufferfish are poisonous.
Water Requirements for Freshwater Puffers
If you plan on keeping a freshwater pufferfish as a pet, it is very important to study it carefully. Determine the exact water parameters (pH, temperature, etc.) your particular species needs. This is very important for your pet’s survival.
Here are some approximate water parameters for most freshwater pufferfish.
- Water pH – Freshwater pufferfish need water with no salt and with a pH between 7.0 and 7.6.
- Water-flow – This varies from species to species. However, most require moderate to fast-flowing water so you’d need some rotating power heads to create a current in the aquarium.
- Water hardness – This needs to be between 8 to 12 dKH (dKH is the measure of carbonate hardness).
- Temperature – Freshwater puffers need water temperature between 74 and 78 F.
- Ammonia – Pufferfish are very sensitive to ammonia. It should always be 0 ppm.
- Nitrites – Nitrite levels above 0.75 ppm in water can be very stressful to puffers.
- Nitrates – Nitrate levels from 0 – 40 ppm are usually safe for puffers, but less than 20 ppm is always safer.
- Oxygen – a dissolved oxygen content of 5-7 ppm is adequate for pufferfish.

Are Freshwater Puffer Fish Good Pet Fish?
Freshwater puffer fish are definitely interesting and unique pets to keep. You will never need any other conversation starter when you invite people over – the chubby and cute-looking puffer fish is all they will talk about!
However, pufferfish are definitely not good starter pets. They need plenty of care and upkeep. They also have stringent needs as far as their environment and water quality are concerned.
Without these, your delicate puffer will not thrive. They are especially very sensitive to ammonia, nitrate, and nitrite levels. Even a slight increase in these parameters could stress them out.
However, once you learn exactly what your species of freshwater puffer fish needs, then keeping one can be a highly rewarding experience.
Remember: some species of puffer fish need a very large tank – larger than the average freshwater fish needs. Some species like Mbu freshwater puffer grows up to 67 cm in length!
Moreover, they are not community fish and are known to bite or nip the fins of their tank mates. So, it may be best to house them alone.
If you plan on adopting a puffer fish, please make sure it is a species meant for captivity. And whether you adopt or buy your pufferfish from a local fish/pet shop, please learn all you can about the particular species. Research the species’ exact needs. Continuously monitor your pet and make water changes as recommended.
