Freshwater Puffer Fish Care – What do Puffer Fish Eat?

Freshwater Puffer Fish are chubby, yet cute looking animals that can be found all over the world. They come in many colors and sizes from small ones like bettas to huge puffers more than two feet long! The most interesting thing about these tropical creatures is their hunting technique: instead of using sight or sound like other types do (such as needle-like teeth), they rely on smell with an extraordinary sense called “osmoreceptor” which helps puffs find prey underwater by detecting changes from salt content in water.

Freshwater Puffer Fish Characteristics:

One of the most interesting things about freshwater puffer fish is that they have a diet characteristic to all types of puffers. Some of the foods you can give it includes shrimp, krill, insects, worms and small crustaceans. They also eat algae and other plants while in the wild. Freshwater puffers should be fed once or twice a day depending on how many times your particular puffer eats. This will vary from fish to fish because not all puffers are one size fits all.

Freshwater Puffer Fish Origin:

As mentioned before, these unique little creatures come from many different parts of the world including Japan, China, Southeast Asia and India where there are lots of rivers and shallow ponds for them to live.

Freshwater Puffer Fish Size:

As for size, freshwater puffer fish can grow anywhere from eight inches to over two feet long! Some larger species can even weigh more than five or six pounds which is more than most dogs! This is why it’s important that you put them in large tanks so they have the space to swim around and exercise. Their growth rate also depends on their environment, diet, tank mates and other factors like water PH.

Freshwater Puffer Fish PH:

Just like saltwater fishes, fresh puffers require a certain level of pH in their habitat that isn’t too high or low. A good range would be about 6-8 but if it gets any lower or higher then they will start to get sick and eventually die. The ideal water temperature for most species would be anywhere from 70-80 degrees Fahrenheit (21-25.5 Celsius).

Freshwater Puffer Fish Colors and Markings:

These fish can come in a variety of colors such as yellow, green, brown or black like the picture above. Some may even have stripes while others spots but they’re typically not too colorful since most species are found in dark rivers and ponds with lots of plants and shrubs around it. Their markings also vary depending on species and sometimes you might see them change color when mating or fighting another puffers for dominance.

Freshwater Puffer Fish Aquarium:

Since these unique little creatures can grow up to more than two feet long, you’ll want a large tank at least 60 gallons for one puffer and anything over 100 for two or more. It’s also important that the glass is thicker so they don’t try to smash through it because if they do manage to break it then you could have a dead fish on your hands! A good filtration system is required as well since puffers are messy eaters and will produce lots of waste throughout the day.

Freshwater Puffer Fish Tankmates:

Puffers can be kept with other tropical fish but just keep in mind that some breeds are really territorial and might attack other fish either by chomping at their or eating them entirely! There are a few options for tankmates you can try out such as bigger types of cichlids, characins and even turtles. Just make sure they’re not a danger to the puffer by being too aggressive or eating them! Also avoid any sharp objects because these guys have super sensitive noses which might get hurt from something like a coral reef.

Freshwater Puffer Fish Care:

Freshwater puffers are very easy to care for but just keep in mind that puffer fish require special attention compared to other breeds. The most important thing is that their water temperature has to be right otherwise they could get sick or die within a short amount of time. Another thing is that underfed puffers tend to become more aggressive because they will try to protect their territory by chasing other fish around. If you have more than one puffer then it’s really important that you feed each one of them at different locations because they are cannibals!

Freshwater Puffer Fish Lifespan:

While there is no general answer for how long freshwater puffers can live, most types typically only survive about five years or so in the wild but some rare species can live up to twenty which isn’t bad compared to dogs or cats! Just keep in mind that if your puffer starts to look beat up with scars all over its body, it might be losing a fight for its territory with another fish and could eventually die from those injuries. It’s also worth mentioning that some puffers might regrow their teeth or even the entire body parts that are damaged.

Freshwater Puffer Fish Diet and Feeding:

Feeding your fresh puffer fish is not too difficult since they will basically eat anything you give them but make sure it’s all natural. You can feed them things like snails, shrimp, crabs, clams frozen krill, blood worms and even frozen cubes made especially for tropical fishes! Just keep in mind that some types of food might be harmful if given excessively so follow up with care when feeding your puffer fish.

Freshwater Puffer Fish Differences:

There are about 120 different species of freshwater puffers around the world but are three main differences between them: the teeth, their color and markings and how many spikes they have on their back. The first one is fairly obvious because some breeds just have regular teeth that point straight forward while other types might be more crooked or even look like a crab’s pincers! Some puffers may even carry venom in those chompers so you should be careful if trying to feed them something by hand.

The next difference is color and markings which can vary from black with white spots, to orange with black stripes or sometimes even purple with yellow stripes. You’ll also notice that males tend to be bigger than females as well as show brighter colors during mating season but if they’re not getting along then these features disappear quickly. last thing is the amount of spines some types have on their back since it can range from two to ten!

Freshwater Puffer Fish Breeding:

Caring for fresh puffer fish is not too difficult if you know what you’re doing but breeding them is a whole different story! It’s actually more complicated than what you would think because puffers will only start mating if the water temperature is right and they have plenty of food in front of them. Also remember that it’s really illegal in almost every country worldwide to attempt captive breeding of a wild caught type or even let them breed naturally in your tank, so please don’t do this unless you want to get fined!


A freshwater puffer fish might seem like a cool pet to have but just keep in mind that they are extremely high maintenance, require specific living conditions and most likely will not be easy to breed! Just make sure you research the “right” type before making your purchase because you don’t want to end up in a bad situation in which your new pet ends up dead within weeks.
