Danio erythromicron DNA sequence data showed that "Microrasbora erythromicron" was related to "Danio", and recommended moving this species to that genus. Later molecular analysis confirmed its placement within the genus, with its closest relatives being "Danio margaritatus" and "Danio choprai". Danio erythromicron Danio erythromicron, often known as emerald dwarf rasbora, is a species of cyprinid fish which is endemic to Inle Lake in Myanmar. In 1999, it was suggested that the species be transferred to the genus "Danio" based on morphological data, but it was cautioned that more research would be necessary. A phylogenetic analysis of "Danio" found it indeed close to
