This extraordinary #beauty is a real #dwarf (maximum length around 2.5 cm). It originates from the southwestern province of #Ranong in #Thailand (which forms a border to #Burma) and is now available in perfect quality. Initially this fish has been described in the genus #Microrasbora, but has been transferred together with M. #gatesi and M. #nana in the new genus #Microdevario in 2009.
The peaceful schooling #fish is a perfect species for the so-called #nano-aquaria. In the wild, they inhabit #brooks and so they need clear, clean and oxygen-rich #water. The temperature should be between 22°C and 26°C. Water #chemestry is of no relevance as long as extremes are avoided.
One should keep in mind that the brilliant green stripe can be seen only when the light comes from ahead and arrange the illumination of the #tank in an appropriate way.
