Green Spotted Puffer Tank Setup and Tankmates. The Green Spotted Puffer (GSP) is a highly aggressive fish that may attack and kill any other fish or critter in the tank. Many puffer keepers feel they should not be kept with any other fish species, or even other puffers. It is usually wise to keep a Green Spotted Puffer alone in a single-specimen tank. They do not belong in a community aquarium, even as juveniles, and even if the pet store said they are freshwater fish.
