Galaxy Rasbora / Celestial Pearl Danio

Galaxy Rasbora (Danio margaritatus)

The Galaxy Rasbora, also known as the Celestial Pearl Danio, is a breathtaking nano fish prized for its deep blue body covered in shimmering pearl-like spots and vibrant red-orange fins. Native to small ponds and wetlands in Myanmar, this stunning species quickly became one of the most sought-after aquarium fish due to its unique appearance and captivating behavior.

Known for their peaceful temperament and active nature, Galaxy Rasboras thrive when kept in groups of six or more. They are most comfortable in densely planted aquariums with plenty of cover, open swimming areas, and gentle water flow. Their striking coloration becomes even more vibrant in well-maintained planted tanks, where the contrast between their spotted bodies and colorful fins creates a truly eye-catching display.

Galaxy Rasboras are an excellent choice for nano and community aquariums, especially when housed with other small, peaceful species. While they can be somewhat shy at first, they quickly become more confident in larger groups. Their extraordinary coloration, fascinating social interactions, and manageable size have made them a favorite among aquascaping enthusiasts and nano fish keepers alike.
