Like all the pufferfish, the Green Spotted Puffer can vary greatly in temperament from one individual to another. They are generally regarded as aggressive fin-nippers and often kept singly. However they can be kept in a community setting with others of their own species as well as other large non-aggressive species. In a community setting, be sure there is plenty of room and that the aquarium is well planted. It can also have a variety of other decor such as rocks and roots. Place the decor in a manner that breaks their line of site and provides plenty of retreats for all the fish.
