Fish - Discus Fish

Discus belong to the genus Symphysodon, which currently includes three species: : The common discus (Symphysodon aequifasciatus), the Heckel discus (Symphysodon discus), and a new species which has been named Symphysodon tarzoo [1]. However, a further investigation published in August 2007 [2] suggested that the genus held the three species: S. aequifasciatus (the green discus), S. haraldi (the blue/brown/common discus) and S. discus (the Heckel discus). Both studies suggest three species; the only disagreement is in the scientific names for each.
