Celestial pearl danio: Complete Guide To Care, Breeding, Tank Size, And Disease

Celestial pearl danio (or Celestichthys margaritatus) are a popular freshwater fish species, native to the shallow streams of Myanmar. They are known for their vibrant colors, their small size, and for their peaceful temperament. Keeping these fish in a home aquarium is a rewarding experience, but there are certain guidelines that need to be followed to ensure that they thrive.

To start, the tank should be at least 10 gallons in size and equipped with a filtration system. Celestial pearl danios prefer a neutral to slightly acidic pH of between 6.5 and 7.5, and a temperature of between 68 and 79 degrees Fahrenheit. The tank should also be well-planted, as these fish prefer densely-vegetated habitats. In addition to a good filtration system, the tank should also be equipped with a heater to maintain the optimal temperature.


Celestial pearl danios are omnivores, so they should be given a variety of foods. A good diet should include a combination of high-quality flake and pellet food, as well as occasional treats such as frozen or live brine shrimp, daphnia, and bloodworms. These fish should be fed small amounts of food several times a day.

These fish do best in groups of at least six, so they should be kept in a school. As they are peaceful fish, they can be kept with other peaceful species such as tetras and rasboras. It is important to note, however, that celestial pearl danios can be quite active and may out-compete their tankmates for food.

Celestial pearl danios are hardy fish that are relatively easy to care for. With the right setup, a good diet, and regular maintenance, these fish will thrive in the home aquarium.

Once the aquarium is appropriately set up, it’s time to introduce the breeding pair of Celestial Pearl Danios. The male and female should be placed in the tank together, and they should be of similar size and coloration. If the pair is compatible, they will begin a courtship dance and spawning can begin.

During spawning, the female will lay her eggs on the sides of the tank or on the plants in the aquarium. After the eggs have been laid, it is important to remove the adults from the tank to prevent them from eating their own eggs. The eggs will hatch after two or three days and the fry can then be fed with a newly hatched brine shrimp diet.

Once the fry have grown to a size of about one inch, they can be moved to a separate tank. With the proper care and maintenance, Celestial Pearl Danios can be kept and bred for many years. Through proper breeding, aquarists can create their own unique variations of this beautiful fish.
