|Size:||Grows to no more than 20mm TL
|Comments:||This is a very pretty species that will do well in a small species aquaria. It is tolerant of water conditions but will show its best colours in soft water. It is not a difficult species to spawn and raise. A detailed account of this can be found here.
Kottelat & Witte in 1999 reassigned Microrasbora erythromicron to the genus Danio on the basis of the Danionin notch in the lower jaw and a median process on the pleural rib of the fourth vertebrae. Dr Fang(1) was unable to find any specimens with the Danionin notch but confirmed the median process. (This is a derived character shared with Danio). Other characteristics with regard to bone structure and formation were dissimilar to those of Danio.
