Try posting in the puffer forum. You'll get more responses. Is your tank (filter) fully cycled? Fish don't starve in 4 days. Most fish can live for weeks with no food.

First of all, you CAN'T change freshwater to brackish water overnight.
Second, Pacu don't live in brackish water and need tank as large as 500+ gallons or even better thousand gallons or outside pond to live for life.
Third, your tank is not even cycled yet and can't not handle the heavy bio load from those fish, with your sudden change the water salinity, you're pretty muck messed up the tank cycled if it was proper cycled.
*Your best option is return the Pacu and the puffer until your tank is cycled, if you decided to keep the puffer then pretty much you will have to do daily water change for next few weeks until your tank proper cycled and don't feed live feeder to your puffer. Next is spend all your free time search this forum or google about cycling your tank and how to keep your puffer happy.

Its unfortunate that this hobby has such a barrier to entry on preparation and information required. A lot of the big box type stores won't fill you in on this to make the sale.
Theres a bit of knowledge required before hand. Stuff having to do with beneficial bacteria colonies in your tank that break down chemicals produced from the fish into less harmful compounds.
Youtube is a great resource on this. Educate yourself on the "cycling process"
Everything my friends have mentioned before me is true. I would encourage you to take the fish back and get your tank stabilized and running correctly. Theres a good chance all your fish will die in the next 36 hours if you do not. You also have some issues with fish selection and compatibility. Trust me I get it, I want to keep em all too!

But in order to achieve success in this hobby you have to do some homework first. But I guarantee you its worth it.

Things I think you should look into
-cycling
-water changes and general up keep
-fish compatibility (size, aggression, type of water, temperature)
-testing your water parameters Primarily ammonia nitrite and nitrate
