With the objective of knowing the diversity of ornamental fish during the dry season, a study was carried out in the lower basin of the Pucacuro River, within the limits of the Pucacuro National Reserve (RNPU), between the months of October and November 2019. The data was obtained by capturing fish using trawl nets or cloths with a small mesh opening of 0.2 - 1.2 cm and variable length and pusahuas with a small mesh bag of 0.2-1.0 cm in 6 sampling points. Thirty species were registered, of ornamental fish corresponding to 6 orders and 11 families, reaching 65.97% of the species expected for the area. The orders with the greatest number of registered species were Characiformes (15 species, with 50%) and Siluriformes (8 species, with 26.67%); at the family level, Characidae obtained 11 species (36.67%) and at the sampling point level, Boca Aleman was the most diverse with 18 species. It captured 860 individuals, the species Hemigrammus sp. was the most abundant compared to the other species (423 ind., with 49.19%), being even the most captured species in all the sampled points, except for Playa Bamunti, where Nannostomus mortenthaleri was the most abundant (38 ind.). The dominance of Simpson was greater in Quebrada Nelia (0.4243), while the similarity analysis indicates that there are few shared species among the sites studied. In conclusion, the group with the highest diversity was Characiformes and species with very low abundances were recorded
