Hasemania is a genus of characins endemic to Brazil, where only found in river basins that originate on the Brazilian Shield, ranging west to the Juruena system, north to the São Francisco system and south to the Paraná system.[1][2] The individual species generally have quite small ranges and two, H. crenuchoides and H. piatan, are considered threatened by Brazil's Ministry of the Environment.[3]
They are small fish, up to 2.7–7 cm (1.1–2.8 in) in standard length depending on the exact species.[1]
