Galaxy Rasbora (Celestial Pearl Danio)
The Galaxy Rasbora (Danio margaritatus), also known as Celestial Pearl Danio or CPD, is a breathtaking nano fish that took the aquarium world by storm after its discovery in 2006. Despite their tiny size (approximately 1 inch), these fish display colors rivaling much larger species—deep blue-black bodies covered in pearl-white spots, vibrant orange-red fins, and a confident personality that belies their diminutive stature.
Males are particularly stunning during breeding displays, where they spread their fins and show intensified coloration while performing courtship dances. These active schooling fish work beautifully in nano aquariums starting at 10 gallons and are perfect centerpieces for heavily planted setups where their colors truly pop.
Native to small, vegetated ponds in Myanmar, Galaxy Rasboras thrive in well-planted aquariums with stable water parameters and temperatures between 72-76°F. They prefer slightly alkaline water (pH 7.0-7.8) and benefit from moderate water flow. Keep them in groups of 6+ for the most natural behavior and breeding activity.

Reviews
I picked up 8 of these celestial pearl danios from aqua atomic and couldn't be happier. They have great color after they settled in, and they're fun to watch. They helped make my emerald rasboras feel brave enough to come out so it's almost like doubling my money, now I can see all my pretty mini-fish.
