I advocate providing suitable environments for the fish we keep, not making the fish "survive" in a foreign environment as this will cause stress and health issues. And it is not fair to the fish that have no means of escape. I am not a puffer fish expert, but here is a passage from an acknowledged puffer site that is pertinent:
Some people use fake, plastic plants and decorations. Some people use some fake decorations and some real decorations. Still, there are others who will only use live plants and real decorations. This is really up to the hobbyist since the puffers don't care either way. The one thing that is very important with a Dwarf Puffer tank is that no matter what kind of plants you use, you want to use a LOT of them!
Dwarf Puffers need places to establish territories and will do best in heavily planted tanks. The plants also break their lines of sight and will cut down on their aggression towards one another. The other purpose that the plants serve is to add complexity to their environment. In a more interesting habitat, the puffers' curious and explorative nature can really be seen. They won't spend so much time swimming up and down the glass out of boredom.
It's also a good idea to add multiple caves/hiding spots throughout the tank. This will give the puffers a place to escape if they feel threatened.
The aquarium is the environment in which the fish must live and to do that it has to be designed for the fish, not our personal wants.
