Many thanks to Lexcy in Abbotsford, BC for all the information below.

These puffers orignate in freshwaters of Southeast Asia and are said to be a little nippy.  I have them in a tank with my other pufferfish and haven't had any kind of a problem.  I have also heard personal stories from pufferfish owners that they nip, so take extra precaution when introducing them to a new tank.  Figure 8s are said to be brackish water fish , but there is still quite a debate on whether this is true or not.  Most hobbyists would say to add some salt, but not much.  Salt is good for most freshwater fish, as it kills bacteria if they have a wound.  It's not bad in proper quantities.
