All piranha information that is linked from this page is original work based on the scientific papers and museum documents describing these fish; we also include first-hand accounts from aquarists that actually keep these piranha, it is not from second hand accounts or other websites. This page is provided for piranha informational purposes only. The pages linked here are a work in progress and will be updated or changed as information is determined to be invalid or more complete data can be obtained. Use it to link to piranha pictures and additional information about the fish listed. We have also begun construction of piranha general information pages. These pages will attempt to provide basic information about keeping piranha, their history, current trends in the hobby and ideas about the future of piranha in the hobby. You can find this new information using the Piranha Info link located at the top right of our pages.
