Listed below are many of the freshwater and brackish diseases that you may have to deal with.  Since most aquarium pathogens are largely unfamiliar by their scientific name, they are listed below by their common ones.  When treating pufferfish, pay special attention to the fact that they are scaleless.  Some medicines in normal dosage can damage their skin.  Being scaleless also makes them more susceptible to certain parasites.  If you are unsure about the specific pathogen(s) infesting your tank, use the Diagnostic Flowchart.  Always rule out environmental illnesses first.  If you know what your fish is suffering from, click away...  *photos are extremely helpful in diagnosis.  If you have any pictures of puffers with the following diseases/illnesses, please email them to Puffernet.  Credit and thanks will be gladly given.  Additionally, if you don't see a particular illness you are searching for, contact me, as I may have access to that information.
