Celestial Pearl Danios live among dense vegetation in marsh areas fed by springs or in small ponds of cool high altitude wetland regions in South East Asia. The water needs to be slightly alkaline, and the temperature shouldn't be to warm.
To date, they have come across this species in a small mountainous area near Hopong East of Inle Lake in the outskirts of the Shan state capital of Taunggyi and the Southeast Asian nation of Burma
The Galaxy Rasbora has a tiny mouth, so you need to take into account the size of the food.
This species is not choosy eaters and will happily eat high-quality commercial dry flakes, pellets and granules, but as they tend to stay in the bottom and mid-levels, sinking pellets would be more appropriate.
This species will also eat small live or frozen foods such as brine shrimp, blood worms, daphnia and cultured white worms which will keep their colours vibrant.
If these foods aren't readily available, they will happily eat algae and plants.
