The celestial pearl danio (Danio margaritatus), often referred to as the Galaxy Rasbora or simply CPD, is a strikingly beautiful fish that has captivated aquarium enthusiasts since its introduction to the hobby. Discovered and officially described only in 2006, this small, vividly colored fish has quickly become a favorite among fishkeepers.
Native to Myanmar, the celestial pearl danio is renowned for its dazzling appearance. It features a unique combination of iridescent blue and bright orange spots that create a celestial effect, resembling a galaxy of stars. Its compact size, typically reaching just about 1 inch (2.5 cm) in length, makes it an ideal addition to smaller aquariums.
In addition to its visual appeal, the celestial pearl danio is appreciated for its peaceful and social nature. It thrives in well-maintained aquariums where it can be kept in schools of at least six individuals, allowing its natural behavior to shine. The species is relatively easy to care for, adapting well to a variety of water conditions and dietary options.
