it's actually both. there are fresh water puffers and saltwater puffers and brackish water puffers. the fresh water ones tend to be large (2ft for some species) for a more accurate answer i need a species name for the puffer
Fresh water
Both kinds of fish can live in a delta area. The line between salt water fish and fresh water fish seems to be getting blurrier. Sharks and other typically salt water fish are found many miles up stream in rivers that empty into the ocean. It appears that salt water fish adapt better than fresh water fish as the fish found in fresh water are not found out at sea.
Lets See If This Answers Your Question... Fresh Water Fish have A Liver That Can Process All Kinds of Stuff From Fresh Water. Wether It Be Dirty Water, Clean Water, or Sometimes Even Slightily Toxic Water... But The Transition To Fresh To Salt Lies In The Very Word Itself, SALT WATER... The Liver of A Normal Fresh Water Fish Can Only Handle Bits of Amount of Salt, But The Water In The Ocean Is So Strong That The Liver of A Fresh Water Fish Just Over Loads and Shuts Down Killing The Fish... Thats Why Salt Water Fish Have Evolved Their Livers To With Stand Lethal Amounts of Salt In The Water... The Same With Salt Water Fish, They Can Not Process Fresh Water Because their Livers Are Only Made To Process Salt Not Fresh... Some Fish Actually Can Do Both Like The BULL SHARK, Salman, (not a fish) Salt Water Crocidile...

It depends on the type of fish. If it is a saltwater fish than it lives in salt water, but if it is a fresh water fish than it lives in freshwater.
They are from tidal eastuarys in the tropics and so are capable of handling both sea and fresh water. They should be OK for a couple of years or so provided there is at least some salt in the water.
