When it comes to pufferfish, most people only think about the many different saltwater species.<\/p>\n

However, you may not know that there are tons of beautiful freshwater pufferfish available to keep in your aquarium that are equally as unique and challenging as their saltwater counterparts!<\/p>\n

Pufferfish are known for their distinctive appearance and their even more unique behavior, especially when they are feeling threatened.<\/p>\n

They will typically inflate to a much larger and rounder size when a predator approaches them and also contain a venom named tetrodotoxin, which is extremely dangerous.<\/p>\n

\"\"<\/span><\/p>\n

Due to these unique characteristics and the fact that they require very good water quality as well as a lot of space, freshwater pufferfish are not that easy to care for.<\/p>\n

I would recommend pufferfish to hobbyists that have more experience, especially with managing large tanks, and wish to challenge themselves with this unique species.<\/p>\n

They might be difficult to care for, but as most of you know with higher care level fish \u2013 the rewards are massive!<\/p>\n

In this guide we will not only be looking at each of the freshwater pufferfish available to freshwater fish keepers, but their requirements, behavior, compatibility, and much more.<\/p>\n

Freshwater Pufferfish List<\/h2>\n

Due to each freshwater pufferfish having their own characteristics and tank requirements, instead of giving you a general overview of all the different subspecies, you will be provided with the individual requirements and specific information regarding each subspecies.<\/p>\n

Something important to note before diving into the list is that you probably will be wanting to avoid tank mates for your puffer fish.<\/p>\n

I say this because the freshwater species that feature on my list are all pretty aggressive fish and have bad tempers paired with incredibly big teeth \u2013 not a good combination!<\/p>\n

Make sure you avoid community tanks with your puffers and avoid any slow-moving, smaller fish as they might not survive too long. All in all, puffer fish are better off alone than with tank mates, especially other puffer fish!<\/p>\n

Now, let\u2019s dive in to the list!<\/p>\n

Dwarf Puffer Fish<\/h3>\n

The dwarf puffer fish (Carinotetraodon travancoricus) is one of the most popular freshwater pufferfish, and they actually do not require as much experience and overall maintenance as the other puffers that are featured here.<\/p>\n

This is due to their incredibly small size, only growing to a maximum length of 1.4 inches (3.5 cm), and the fact that they do not have endlessly growing teeth either.<\/p>\n

This enables you to get away with housing them in a smaller tank compared to some others on my list.<\/p>\n

Dwarf pufferfish sport bright coloration, a yellow\/green body paired with some interesting black spots, their eyes are large in comparison to their bodies, which can be rather amusing.<\/p>\n

You can easily keep one dwarf puffer alone in a small tank, a 10 gallon freshwater tank<\/a> (45.5 Liters) is perfect for them as they can still be fairly territorial and aggressive, which requires them having their own space.<\/p>\n

For a graphical representation of their various requirements, take a look at the image below that I created:<\/p>\n

\"\"<\/span><\/p>\n

If you wish to keep them with other fish, do so, but ensure that your tank is large enough for them to establish a clear territory away from other inhabitants.<\/p>\n

I would suggest a 20 gallon (75.7 liters) tank as the minimum size should you wish to keep them with other freshwater fish.<\/p>\n

They are carnivores that require small, meat-based foods, but try and balance it out and feed them a good variety of different foods. Such as frozen bloodworms and brine shrimp, with the addition of live foods like blackworms or snails.<\/p>\n

Feeding them live food will stimulate them and bring out their natural hunting instinct that can be difficult to replicate outside of the wild.<\/p>\n

Dwarf puffers, or pea puffers, require a tropical freshwater temperature ranging between 74\u00b0F and 82\u00b0F (23.3\u00b0C \u2013 27.7\u00b0C) to live comfortably.<\/p>\n

Fahaka Puffer Fish<\/h3>\n

Now, let\u2019s go from the smallest freshwater pufferfish breed to one of the largest – the Fahaka puffer fish (Tetraodon lineatus) is certainly one of the biggest puffers you can keep, growing to an incredible 16 inches (40.64 cm).<\/p>\n

Due to this, they will need a pretty large tank \u2013 I suggest 150 gallons (570 liters) as a minimum. This gives them plenty of space to move around in and grow to their max size without you having to increase the size of your tank.<\/p>\n

Regarding their aquarium environment \u2013 they will need plenty of plants and vegetation, as well as powerful water filters to ensure the water quality is good enough for them as they are very sensitive to poor water quality.<\/p>\n

The graphic I created below showcases all of the specific information and requirements for the Fahaka Puffer Fish:<\/p>\n

\"\"<\/span><\/p>\n

Unlike the dwarf puffer fish, these guys are almost always aggressive and mean fish<\/a>. They can even be pretty aggressive toward their human owners, with their incredibly sharp and human-like teeth seemingly never stopping to grow. Be careful when feeding one as it could be goodbye to your fingers!<\/p>\n

This leads us on to look at their diet. They are carnivores, but interestingly enough are referred to as molluscivorous, which means that they typically eat oysters, krill, cockles, and mussels rather than other fish.<\/p>\n

In terms of their appearance, it is unusual to say the least. They showcase bright orange\/red eyes and are covered with short spines across their bodies.<\/p>\n

Their bodies are gray\/brown in color with a lighter shade on their bellies extending from their pectoral fins to their tails.<\/p>\n

Congo Pufferfish<\/h3>\n

Congo pufferfish (Tetraodon miurus) do not leave much to the imagination regarding their origin, they typically reside in African rivers and they like to bury themselves in sand to hide away from predators.<\/p>\n

Unlike the other two puffer fish mentioned, the Congo puffer is medium\/small in size, reaching a maximum of 3.9 inches (10 cm) in length.<\/p>\n

They adapt pretty well to most environments and are not as aggressive as their Fahaka cousins. 40 gallons is the perfect size tank for them (151.4 liters) to feel both free and comfortable in.<\/p>\n

Also, they are fairly mild-mannered for pufferfish too, typically getting along well with other fish of a similar size and nature.<\/p>\n

If you wish to know their requirements in a detailed and graphical format, then take a look at the graphic I created of the Congo puffer fish overview below:<\/p>\n

\"\"<\/span><\/p>\n

Overall, they are pretty peaceful, especially for puffers, but you still need to add tank mates with caution. Do not keep them with tons of different fish, and if you do plan on building a community around them, then I would strongly suggest keeping them in a 70 gallon (318.22 liters) tank or larger.<\/p>\n

Other Freshwater Pufferfish<\/h3>\n

We have now covered the most popular and common freshwater puffers amongst hobbyists, but there are a few more subspecies to mention:<\/p>\n
