What is it about?
Being endemic to the Brahmaputra basin of northeast India, the freshwater fishes namely Badis dibruensis and Lepidocephalichthys arunachalensis lack any data on their biology except for few taxonomic comparisons. The present article provides the first report on the length weight relationships for these two species.

Why is it important?
Length weight relationships are important to understand the condition of a fish species in its native environment, and are a preliminary step towards understanding the growth dynamics of a fish species across or related species within the same genus. Therefore the present data will be useful for online fish databases helpful for fishery biologists as well as conservationists.
Perspectives
Badis dibruensis and Lepidocephalichthys arunachalensis have very restricted populations. But they are often misidentified for their commonly available counterparts namely Badis badis and Lepidocephalichthys guntea. Thus most studies on their biology seem to be erroneous or biased especially from the northeastern region of India. The present article aims to provide valuable insights to the growth dynamics of these two fish species with correct identification. However, the present study had been covered for a 12 month period only, and thus warrants further studies across other habitats for these two species (if available), necessary to confirm and rely on the same.
