Scientifically named Danio margaritatus, this enchanting species hails from Myanmar and is a favorite among aquarists for its starry pattern and vibrant colors, which bring a touch of celestial beauty to any aquarium.

Scientific Name: The Celestial Pearl Danio is scientifically known as Danio margaritatus. This species is a member of the Cyprinidae family and is sometimes called the “Galaxy Rasbora” due to its star-like spots.

Water Quality and Temperature: To keep your Celestial Pearl Danio healthy and thriving, replicate its natural environment with the following water parameters:

• Temperature: Maintain a temperature range of 72°F to 79°F (22°C to 26°C) for optimal comfort and health.
• pH Level: Keep the pH level between 6.5 and 7.5 to mimic their natural soft, slightly acidic to neutral waters.
• GH Level: Aim for a general hardness (GH) level between 2 to 10 dGH, which suits their preferred water conditions.
• KH Level: Maintain the carbonate hardness (KH) within the range of 2 to 8 dKH to ensure stable water chemistry.

Feeding: The Celestial Pearl Danio is an omnivorous fish that enjoys a varied diet. To keep them healthy and their colors vibrant, provide a mix of:

• Flake Foods: High-quality flake foods designed for small tropical fish.
• Pellets: Micro-pellets or nano pellets suitable for small fish species.
• Live or Frozen Foods: Offer live or frozen foods such as daphnia, brine shrimp, and micro worms to provide essential protein and encourage natural foraging behaviors.
• Vegetables: Occasionally include finely chopped vegetables like spinach or zucchini to provide additional nutrients.

Tank Mates: The Celestial Pearl Danio is a peaceful species that thrives in a community setting with other small, non-aggressive fish. Suitable tank mates include small tetras, rasboras, and other small danios. Avoid housing them with larger or more aggressive fish, as the Celestial Pearl Danio may become stressed or intimidated by boisterous tank mates.

Substrates and Tank Decorations: Use a fine substrate such as sand or smooth gravel to create a comfortable environment for your Celestial Pearl Danios. Incorporate plenty of plants, driftwood, and small rocks to provide hiding spots and create a natural, lush environment. These fish enjoy exploring their surroundings and will thrive in a tank that offers both open swimming areas and dense plant coverage.

Suitable Plants: The Celestial Pearl Danio appreciates a well-planted tank that mimics its natural habitat. Suitable plants include Java Moss, Anubias, Cryptocoryne, and Vallisneria. These plants provide excellent cover, reduce stress, and create a visually appealing environment for your danios.

Sexing: Sexing Celestial Pearl Danios is relatively easy. Males are typically more vibrant, with brighter colors and more intense spots, especially during breeding displays. Females are generally slightly larger and rounder, with a more subdued coloration.

Breeding: Breeding Celestial Pearl Danios in captivity is relatively straightforward with the right conditions. Provide a separate breeding tank with fine-leaved plants or a spawning mop where the female can scatter her eggs. After spawning, remove the adults to prevent them from eating the eggs. The eggs will hatch in about 3 to 4 days, and the fry can be fed infusoria or finely crushed flake foods until they are large enough to consume more substantial foods.

Maximum Size and Longevity: The Celestial Pearl Danio typically grows to about 1 inch (2.5 cm) in length. With proper care, they can live up to 3 to 5 years, offering long-term enjoyment in your aquarium.

General Information: The Celestial Pearl Danio is a small but stunning fish that adds a touch of celestial beauty to any aquarium. Its peaceful nature and compatibility with other small fish make it an excellent choice for nano tanks and community aquariums. By providing them with the right care and environment, you can enjoy their vibrant colors and lively behavior for years to come.

A Fun Fact: The Celestial Pearl Danio was only discovered in 2006, making it a relatively new addition to the aquarium hobby. Despite its recent introduction, it has quickly become a popular species due to its dazzling appearance and peaceful demeanor.
