Celestial Pearl Danio, scientifically known as Danio margaritatus, is a small and captivating freshwater fish species native to the shallow streams and pools of Myanmar (formerly Burma) in Southeast Asia. They are also commonly referred to as Galaxy Rasbora, Microrasbora Galaxy, or simply CPD. Celestial Pearl Danios are highly prized by aquarists for their striking appearance and peaceful nature.

These fish have a compact and streamlined body shape, with males typically exhibiting more vibrant colors and slightly longer fins compared to females. The most remarkable feature of Celestial Pearl Danios is their iridescent scales, which shimmer with a metallic blue-green hue. They also possess a contrasting pattern of dark spots or bars on their sides, adding to their overall beauty.

In their natural habitat, Celestial Pearl Danios inhabit slow-moving and densely vegetated waters, often found in the vicinity of rice fields. When setting up an aquarium for these fish, it is important to replicate their natural environment. Provide them with a well-planted tank, preferably with fine-leaved plants and floating vegetation to create shaded areas. They appreciate a gentle water flow and soft, slightly acidic water conditions.

Celestial Pearl Danios are peaceful and social fish that should be kept in small groups to thrive. A group of at least six individuals is recommended to ensure their well-being and to witness their natural shoaling behavior. When selecting tank mates, choose other peaceful and small fish species that won't outcompete or harass the Celestial Pearl Danios.

Feeding Celestial Pearl Danios is relatively straightforward as they are omnivorous. In the wild, they primarily feed on small insects, crustaceans, and zooplankton. In an aquarium, they will readily accept high-quality dry flakes or pellets as their staple diet. However, it is beneficial to supplement their diet with small live or frozen foods such as brine shrimp, daphnia, or microworms to provide them with additional variety and nutrients.

Breeding Celestial Pearl Danios can be challenging, as they are relatively sensitive and require specific conditions to reproduce. However, under the right conditions, they may breed in a well-maintained aquarium. It is recommended to provide them with plenty of dense vegetation or spawning mops, as well as a separate breeding tank with gentle water flow. The adults should be removed once the eggs are laid to prevent them from consuming the eggs or fry.

In conclusion, Celestial Pearl Danios are fascinating and visually stunning fish that can enhance the beauty of a freshwater aquarium. With their shimmering colors, peaceful temperament, and shoaling behavior, they can create a captivating display. By providing them with suitable tank conditions, companionship in the form of a shoal, and a balanced diet, Celestial Pearl Danios can thrive and become a highlight in your aquatic setup.
