Types Of Pufferfish

Freshwater Pufferfish: Tetraodon lineatus

Common names: Fahaka puffer, Lined puffer, Nile puffer

  • Activity level: active/hunter
  • Adult size: ~18 inches
  • Min tank size: 120 gallons
  • Temperature: 74-80 degrees F
  • pH: 6.0-7.8

Diet: Crustaceans. While your Fahaka puffer is a baby-sub adult, you can offer them a regular diet of snails, shrimp, and a variety of frozen foods, like blood worms, and brine shrimp – you can also cut fish fillets into bite sized chunks. Once they reach adulthood, it will be necessary to purchase some of your food from the grocery store, like whole shrimp, crab legs, mollusks, and clams. As an occasional treat, you can offer your puffer red wigglers, ghost shrimp, and other types of feeder insects – however, it is important to note that ghost shrimp do not hold very much nutritional value. The key for any fish is a varied diet.

Notes: Fahaka’s are a large, active species of freshwater pufferfish. As such, they require a lot of tank room to move around. It is important to note that the standard 150 gallon fish tank set up is too narrow for an adult Fahaka to easily turn around in. Instead, look for a low, wide tank – a 120 gallon fish tank is wider than a show 150, and is more suitable for an adult specimen.

Young Fahaka’s require adequate hiding spots in their fish tank set up, and will bury themselves in the sand if it is provided. The Fahaka is considered an aggressive species of freshwater pufferfish. While some cohabitate with large, hardy tank mates most will eat other fish that they come in contact with – or at the very least, taste test them.

The Fahaka has a relatively fast growing beak, and requires a hard, crunchy diet. Like many other freshwater pufferfish, if they are not provided with enough hard foods Fahaka’s will require manual beak filing, which is very stressful for both pufferfish and owner.

Freshwater Pufferfish: Carinotetraodon travancoricus

Common names: Dwarf puffer, Pea puffer, BB puffer, Malabar puffer

Activity level:active/hunter

Adult size: ~1 inch

  • Life span: 5+ years
  • Min tank: 10 gallons
  • Temp: 74-82 degrees F
  • pH: 6.5-7.2

Diet: Baby snails are an excellent source of food for dwarf puffers, and you can easily breed a snail colony at home. You can also offer your freshwater pufferfish a varied diet of appropriately sized shrimp pieces, red wigglers, and different types of frozen fish food, like blood worms, brine shrimp, beef heart and krill. Just remember to keep the pieces small, a few blood worms makes a decent sized meal. These little guys should be fed twice a day.

Notes: Dwarf puffers are one of the few types of freshwater pufferfish that can successfully be kept with their own species. They are best kept in a species only tank, however, some do well with a cleaner tank mates, like otocinclus – some keepers even report their dwarf puffers cohabitating with different shrimp species. Since adult males can become very territorial with each other, it is recommended to keep a single male in a group of females – 1 male to 3-4 females is a widely accepted ratio.

Dwarf puffer beaks do not grow at a fast rate, so you are less likely to have fish problems with an overgrown beak. However, you still need to offer dwarf puffers a varied diet that includes a large quantity of shelled foods to maintain dental health – baby pond snails and ramshorn snails are perfect for this. They do well in a planted tank, and they enjoy an interactive environment filled with driftwood caves and other hiding places.

Do Pufferfish Have to Eat Snails to Keep Their Teeth Trimmed

Mussels Are Great For Puffers!

There’s no question about it, snails are probably one of the most widely recommended sources of puffer food. They come in varying sizes, they’re easy to breed, and with the exception of piscivorous species, most puffer fish love them. However, this leads many people who are new to keeping puffers to the conclusion that snails are the only hard food that will help keep their puffer’s teeth trimmed, which just isn’t true!

So, what else can your puffer eat that will help prevent their teeth from overgrowing? Well, you’re only limited to the amount of different mollusks and crustaceans that your puffer will accept. For example, the following all make great hard foods:

Half shell mussels, clams and oysters – smaller puffers will scrape their teeth on them and larger ones will bite the shell itself.

Crab legs – they aren’t just for romantic candle lit dinners! Consider getting a tray for your puffer, too. You can break off smaller sections depending on the size of your fish.
Lobster, crayfish and shrimp – as long as they still have their shell on, they make a great hard food. You will need to cut them up first.

Live feeder crabs – just remember that you have to quarantine live food, and you also want to make sure that the crab is an appropriate size for your puffer. Some of the videos people have where they are feeding a crab that is as large as or larger than their puffer end pretty badly.

With that said, snails are probably one of the most economical choices for puffer food out of the bunch. They are easily bred in small tanks, plastic totes and other similar containers, which really cuts down on costs. Ramshorn snails and bladder snails are both perfect candidates for this. However, if you don’t want to breed your own snails, then you can always hit up some local pet stores to see if they have any excess pest snails they wouldn’t mind sharing – just be careful about dropping pest snails directly into your tank.

All live food items, including snails, have to be quarantined before they are offered to your puffer, because if they aren’t they can potentially transmit parasites and disease. You’ve probably noticed that I say that a lot throughout this website, and for a very good reason. It’s a very important aspect of keeping puffers to remember that unfortunately aquarists seem to ignore all too often until some sort of disaster strikes their tank. Think of it like this – would you add a new fish that has been kept around other potentially sick fish to a community tank without quarantining it first? Exactly.

On a final note, just remember that while your puffer doesn’t necessarily have to eat snails, you do have to incorporate some type of hard food into their diet in order to keep their teeth in check. The frequency at which you do this will depend on the species of puffer that you’re keeping – if they have a faster rate of dental growth, like SAP’s (Colomesus asellus), then you will need to provide a very consistent supply of hard food. The key to keeping your puffer healthy is diversifying their diet, so keep in mind that hard foods aren’t the only suitable item on the menu! Mix it up with blood worms, pieces of shrimp meat, fish fillet chunks, live feeder insects, red wigglers…you get the point!
