This is a site dedicated to Puffers. They cover all from fresh to marine and brackish water. The site is easy to navigate and since there are just a few forums dedicated exclusively to puffers, this is one you don't want to pass.
When buying or thinking about buying a puffer the main thing is to make sure you are ready for it. There are several species available in the local fish stores and most are either miss-identified or completely unidentified. Make sure you know if it is a freshwater or a brackish water since the life span of the fish will largely depend on this.
A little research on this will go a long way and sites like the puffer forum make it easier.
