Water Requirements for Freshwater Puffers Freshwater puffers do best at a pH between 7.0 and 7.6, with the temperature between 74° and 78° F. Aquarium salt should not be added to a freshwater puffer aquarium unless it is used to treat diseases. This should not be confused with brackish water species such as Figure 8 and Green Spotted puffers, which are frequently kept in fresh water in aquarium shops and are sold as such. While these fish can be adapted to freshwater, they tend to be more susceptible to diseases, especially ecto-parasites like Ich and Oodinium, when kept this way. If the aquarium is kept in a room below 74°, use an Aqueon aquarium heater to increase the heat. Maintain good filtration and do a 10% water change every two weeks or 25% once a month using an Aqueon Aquarium Water Changer or Siphon Vacuum Gravel Cleaner. Don’t forget to treat tap water with Aqueon Water Conditioner before refilling your aquarium! Housing Requirements for Freshwater Puffers The freshwater puffer aquarium should be well decorated and include caves, grottos and overhangs to provide shelter and hiding places. Aquarium size depends on which species you want to keep. For example, Dwarf Pea puffers (C. travancoricus) can be kept in aquariums as small as 5 gallons, while other species need 20 gallons or more per fish. Some larger species don’t need as much space as you would expect based on their size, because they spend most of their time motionless. Below is a list of recommended aquarium sizes for typically available species:
