Danio erythromicron 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 that genus, but its precise placement was still indeterminable. Shortly thereafter, a new species, "Danio margaritatus", was described under the name "Celestichthys margaritatus". However, this new species was quickly moved into "Danio" following further analysis. Subsequent analysis of
Danionin rerio", "D. nigrofasciatus", and "D. albolineatus"; the remaining "Danio" species were moved to "Devario", which at this time included "D. malabaricus", "D. kakhienensis", "D. devario", "D. chrysotaeniatus", "D. maetaengensis", "D. interruptus", and "D. apogon". The only "Danio" species to have been consistently called "Danio" were "D. dangila" and "D. feegradei". As "D. dangila" was the first discovered "Danio" (or type) the name "Danio" had to remain with "D. dangila", which is why the vast majority of species were moved to "Devario". Also, the sister group to "Devario" was deemed to be a clade formed by "Inlecypris" and "Chela", and more
