Danio margaritatus it cannot be kept with large or "bully" fish. Small, swarming danionins which require similar water conditions would be a natural choice for company, as such more active species provide nice contrast behaviorally and, being available in a wide range of colors and patterns, also make it possible to choose fish that complement the brilliant colors of "D. margaritatus". Many danionins prefer slightly acidic water, however, and maintaining the rather high pH found across the Inle basin seems a necessary condition to keep fish from there successfully. Danio margaritatus Danio margaritatus, the celestial pearl danio, often referred to in the
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
