Puffers have a unique and comical way of swimming. Puffers often nip at the fins of other Puffer and other species of fish. This nipping can be minimized by keeping puffers very well fed. Freshwater Dwarf Puffers do less nipping than many other types of of Puffer Fish. Some species of Puffer Fish live best in freshwater, some other species live best in brackish water, and some Puffers live best in marine or sea water.
Freshwater contains very little salt.
Brackish water has about 1 Tablespoon of salt in each 5 gallons of water. Sea Water has much more salt. Each type of Puffer Fish seems to do best in one of these three types of water. The table below shows the letter B for a species of Puffer Fish that lives best in Brackish Water or the letter F for a species of Puffer Fish that lives best in Fresh Water.
