I was offered a Green Spotted Puffer Fish as a Fresh water fish?

Question

I thought they were Marine Fish.
I didn't take the fish, but I'm thinking about it.
I have over 15 years in keeping Tropicals and Coldwater fish and I was wondering does anyone have one of these fish in a Tropical Fresh water tank, I did a little research and I have come to the decision that young ones are ok in a fresh water tank and as they get older they go into a brackish aquarium and then a Marine aquarium is needed, salt water, coral, skimmer and reverse osmosis unit, the while lot ???

While they are small they can live in fresh water perfectly OK, so that's how they are sold in shops.

But if you want them to live for very long you need to move them to brackish conditions (part sea water). Being brackish fish they can handle a wide range of salt levels as their natural habitat chances in salt level with the weather and tides.

"Specific Gravity : adaptable, from low-end brackish (1.005) up to low-end saltwater (1.20)"

They don't want a full marine set up, brackish is better.
