Celestial Pearl Danio

Aquarium hobbyists are always on the lookout for interesting and colorful fish to add to their tanks. One such species that has gained popularity in recent years is the Celestial Pearl Danio (CPD), also known as the Galaxy Rasbora or Danio margaritatus. This tiny fish with its striking coloration and behavior is a great addition to any aquarium setup. In this article, we will delve deeper into the world of CPD and explore their characteristics, care requirements, and breeding.

The Celestial Pearl Danio is a small freshwater fish that grows up to 1 inch in length. It has a slender body with a round belly and an arched back. The fins are translucent, and the dorsal fin has a black tip. The body is adorned with a striking blue-green iridescence and orange spots. The combination of these colors makes the CPD one of the most attractive aquarium fish.

Habitat and Distribution: CPDs are native to the shallow streams and ponds of Myanmar, where they live in the leaf litter and vegetation along the water's edge. They were first discovered in 2006, and their unique coloration and behavior made them an instant hit among aquarium enthusiasts. Due to their popularity, the wild populations of CPD have suffered from overcollection, and they are now considered an endangered species.

CPDs are relatively easy to care for and can be kept in small aquariums of at least 10 gallons. They prefer a heavily planted tank with plenty of hiding places and soft substrate. CPDs are shoaling fish and should be kept in groups of at least six individuals to prevent stress and aggression. The tank should be well-filtered with gentle water flow, and the temperature should be maintained between 72-82°F.

CPDs are omnivorous and should be fed a varied diet consisting of high-quality flake food, frozen or live foods such as brine shrimp, daphnia, and bloodworms. It is essential to avoid overfeeding as it can lead to health issues and poor water quality.

CPDs are active and playful fish that spend most of their time swimming in the mid to upper water levels. They are shoaling fish and will form tight groups, especially when they feel threatened. CPDs are peaceful and can coexist with other small and peaceful fish such as tetras, shrimp, and snails.

Breeding CPDs can be a challenge as they are difficult to sex and require specific conditions for breeding. The males are typically smaller and slimmer than females and have more intense coloration. They prefer soft, acidic water with a pH range of 6.0-7.0 and temperatures between 75-80°F. CPDs are egg scatterers, and breeding usually occurs in the early morning when the temperature is cooler. The female can lay up to 30 eggs, which hatch within two days. The fry are tiny and require infusoria or powdered food for the first few days before transitioning to small live or frozen foods.

The Celestial Pearl Danio is a fascinating and attractive fish that has captured the hearts of aquarium enthusiasts worldwide. With their striking coloration and playful behavior, they make a great addition to any aquarium setup. CPDs are relatively easy to care for and can be kept in small aquariums, making them a popular choice for beginners and experienced hobbyists alike. It is essential to ensure that CPDs are sourced from reputable breeders to avoid supporting the unsustainable wild collection of this endangered species.
