Chaetostoma, also known as the bristlemouth catfish, is a genus of suckermouth armored catfishes native to South America with one species, C. fischeri, extending into Panama. ^[1] Most species inhabit flowing rivers in the lower Andes and its foothills. ^[2] Some species are kept in unheated aquaria.
