The present paper attempts to document the potential ornamental fishes (POFs) and assess their diversity in two river basins of Arunachal Pradesh that are still unexplored in such a way. Several diversity indices are computed river-wise and statistically compared. From Dikrong and Ranganadi river basin a total of 52 and 29 POF species are documented respectively. The species compositions are quite different in the two river basins may be because of their altitudinal differences. The computed diversity indices are a little confusing because one river is more diverse while the other has more species richness. Hence, diversity profiles are constructed using Renyi index. The intersecting profiles reveal the two river basins are non-comparable in terms of ornamental fish diversity. The paper concludes with the note that compilation of such information would be of immense value practically to generate a river-wise list of POF of the state to design fish conservation strategies in future.
