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
Danio annulosus deep, instead of round or deep wide. No sexual dimorphism is present in Danio annulosus. Healthy adult individuals in life have dark stripes which include circles which are blue in color with the space in between including the circle centres are orange in color. A unique orange spot is seen in the front of the black cleithral spot. The holotype DU 50001 is an adult individual and probable female, 71.5 mm in length and collected form a Chittagong Division, Rangamati District, Borokal, pool at bottom of Shuvolong Waterfall on 28 Nov 2014.
