No. Puffer fish can only survive in the ocean.
The main enemy of puffer fish are sharks, dolphins, and sea turtles, as they are the primary predators of puffer fish in the ocean. Additionally, some larger fish and seabirds may prey on smaller puffer fish.

Yes, the Puffer Fish is a poisonous type of fish.
I'm pretty sure they do, not quite sure sorry :)
puffer fish are ugly
It depends on the maturity and species. Since you didn't mention a species, I can only give you an average weight. - Dwarf puffer fish only weigh just under an ounce. Depending on the species of the dwarf puffer fish - Ordinary puffer fish can weigh 20-30 lbs (9-13.5kg). Again, depending on the species.
puffer fish wake up hunt. Then eat the food. The puffer fish try not to get eaten. so if you like puffer fish or blow fish help them
Normal fish do not puff up- only puffer fish.
