Phycocharax is a monospecific genus of freshwater ray-finned fish belonging to the family Acestrorhamphidae, the American characins.[2] The only species in the genus is Phycocharax rasbora.[3][1] This fish is endemic to the Brazilian Amazon, where it is only known from the upper Braço Norte River (Serra do Cachimbo region), a blackwater tributary in the Teles Pires basin, itself a part of the Tapajós basin.[1] A dam has been built on the Braço Norte River and while the species is uncommon downstream, it is very abundant in the reservoir above.[1]
Its species name refers to the similarity in color and pattern to Trigonostigma rasboras, an unrelated but well-known Asian fish.[1] The mainly reddish males reach up to about 3.4 cm (1.3 in) in standard length, while the duller yellowish females reach up to about 3.1 cm (1.2 in).[1]
