It has indistinct humeral spots (patches near the pectoral fins), and is bluish-silver in life, which is unusual for members of Bryconops; they are more often plain silver or greenish-silver.

[1] A study in 1993 (Chernoff, Buckup, Machado-Allison, and Royero) noted a few different color patterns in gathered specimens of B. inpai, which points to the possibility of multiple species currently considered synonymous, but further research on the subject has not been done.

[8] Since its description by Hans-armin Knöppel, Wolfgang Junk, and Jacques Géry in 1968, B. inpai has been considered a member of the subgenus Creatochanes.

[10] Previously, the genus Bryconops was considered a member of the family Characidae, and several resources still list it as such (like ADW and ITIS);[11][12] however, its current placement is in Iguanodectidae, with Piabucus and Iguanodectes.

[17][18] Bryconops inpai's native range is made up of rivers with very little endemic plant life, which makes it inhospitable to many other species.

[1] Nonetheless, the Rio Negro - as with many other rivers - is under threat from environmental hazards as a result of illegal gold mining in South America, which is a booming industry despite its dangers both to participants and to the environment.
