Dorsal spines (total): 15 - 17; Dorsal soft rays (total): 8-9; Vertebrae: 28. Badis pancharatnaensis is distinguished from all its congeners in having a combination of the following characters: dark brownish black bars on sides present; a series of dark blotches along middle of dorsal-fin present; a prominent black blotch on the superficial part of cleithrum present; elongate median caudal blotch with a posterior bar surrounding the caudal-fin base; pointed pelvic-fin reaching beyond vent in both sexes; pointed soft dorsal and anal-fin; 28.2- 33.8% SL body depth; 7.1-9.4% SL interorbital distance; 14-17 scales around caudal peduncle; 31-33 lateral scale rows; 6-8 gill rakers; and 28 (15+13) vertebrae (Ref. 118053).

Biology     Glossary (e.g. epibenthic)

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).
