Most of the information presented on the Internet says Celestial Pearl Danio prefer soft water parameters. I’m not so sure that is true. Perhaps since many other nano fish come from soft water locations it is just assumed that CPD’s also prefer their water on the soft side.
Shortly after the Celestial Pearl Danio was introduced to the hobby, there was great concern that the little fish were going extinct in the wild. With that concern, a survey of the collection locations for CPD’s was conducted. Mr. U Tin Win made notes and took samples of the water during the survey.
