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.
