XL Celestial Pearl Danio Galaxy Rasbora for Sale in Canada

The Celestial Pearl Danio (Celestichthys margaritatus), widely known in the aquarium hobby as the Galaxy Rasbora, is one of the most sought-after nano freshwater fish. Originally discovered in Myanmar, this spectacular species is famous for its tiny deep-blue body covered with pearl-like white spots and brilliant red-orange fins.

The XL size is especially attractive to aquarists looking for more mature specimens. Larger individuals are easier to observe, display stronger coloration, and can make an immediate impact in a carefully designed planted aquarium.

Despite their small size, Celestial Pearl Danios have an incredible amount of personality. Males frequently display their colours to females and establish small territories, creating fascinating activity throughout a planted aquarium.

Monster Aquarium Canada proudly offers XL Celestial Pearl Danio “Galaxy Rasbora” (Celestichthys margaritatus) with professional live fish shipping throughout Canada.
