Danio erythromicron, often known as emerald dwarf danio and emerald dwarf rasbora, is a species of freshwater ray-finned fish belonging to the family Danionidae. This fish is endemic to Inle Lake in Myanmar.
Taxonomy and systematics
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.{{cite journal | last1 = Kottelat | first1 = M. | last2 = Witte | first2 = K.

Copeia 2003(4): 714–728. DOI:10.1643/IA03-131.1 [http://www.bioone.org/perlserv/?request=get-abstract&doi=10.1643%2FIA03-131.1&ct=1 HTML abstract] Shortly thereafter, a new species, Danio margaritatus, was described under the name Celestichthys margaritatus.{{cite journal | last1 = Roberts | first1 = Tyson R | year = 2007 | title = The "Celestial pearl danio", a new genus and species of colourful minute cyprinid fish from Myanmar (Pisces: Cypriniformes) | url = http://rmbr.nus.edu.sg/rbz/biblio/55/55rbz131-140.pdf | journal = Raffles Bulletin of Zoology | volume = 55 | issue = 1| pages = 131–140 }} However, this new species was quickly moved into Danio following further analysis.{{cite journal | last1 = Conway | first1 = K.
