Etymology: Badis: 'badis' is presumably a Bengali local name, possibly derived from 'bhedo' or 'bheda', but it lacks a proper reference. Probably incorrect etymology (J. Müller, pers. comm., April 2021, after information from native speakers); pancharatnaensis: Named for the historical place called 'Pancharatna' in Goalpara district, Assam, India.

Body shape (shape guide): fusiform / normal.
The type locality is a low lying wetland characterized by dense macrophytic vegetation well connected with the River Brahmaputra and often flooded by the river water, and high degree of rise and fall of water level depending on seasonal climatic variations. Other fish species collected with Badis pancharatnaensis include Amblypharyngodon mola, Anabas testudineus, Channa gachua, Lepidocephalichthys guntea, Mastacembelus armatus, Macrognathus pancalus, Puntius sophore and Trichogaster fasciata which commonly occur in the region. Water quality parameters taken in May 2015 are the following: temperature - 24.8°C, pH- 8.2, DO - 7.8 mgl -1, conductivity - 194 mgl -1and hardness - 81 mgl -1 (Ref. 118053).
