The Celestial Pearl Danio, also known as the Galaxy Rasbora, is known for its great coloration. Most hobbyists relate this fish to a freshwater trout (obviously much smaller though). The Celestial Pearl Danio’s (CPD) coloration consists of bright red fins with white speckles on a deep blue body. This species displays especially vivid coloration when kept in a well-maintained, planted aquarium with optimal water quality. The Celestial Pearl Danio is also an undemanding species, making it suitable for both beginners and experienced aquarists.
Though not a true Rasbora, the name "Galaxy Rasbora" stuck due to their star-like spots on a deep blue body, giving them a galaxy-like appearance. This nickname often causes confusion among hobbyists about whether they are Danios or Rasboras. Their scientific name is Celestichthys margaritatus or Danio margaritatus, confirming they are not true Rasbora species. Despite this, the nickname Galaxy Rasbora remains popular, so it's important to understand its origin.
Celestial Pearl Danios (CPDs) stay small, usually between ¾” to 1” long, making them a great choice for nano aquariums. They are peaceful but can be shy, especially when housed with larger or mildly aggressive fish. If you want them to show their best color and natural behavior, keep them with calm tank mates like shrimp or Rasbora species. A planted tank is perfect for these guys, providing plenty of hiding spots and enhancing their natural behavior.
At Flip Aquatics, we feed our CPDs a variety of high-quality foods including:
All fish orders are covered by our 100% Live Arrival Guarantee. All orders are shipped with reliable shipping methods to ensure the health and safety of the fish during transit. If there are any issues with your order, you may be asked to provide pictures to verify the condition of the fish for a refund or replacement. Shop worry-free knowing your fish will arrive healthy or we’ll make it right. Please allow up to a week for your order to be shipped and delivered, depending on availability.
Maintaining stable water parameters is key, especially during the first week of adding new fish to your aquarium, to help ensure the health and well-being of Celestial Pearl Danios.
You can safely keep 6 to 8 Celestial Pearl Danios in a 10-gallon tank. They do best in small groups and will feel more secure and active when kept together.
Yes and no. Our CPDs are very hardy due to our quarantine process. They often get a bad reputation for being delicate due to most stores not ensuring their health prior to selling. Ours adapt well to most aquarium setups if water parameters are consistent and stress is minimized.
CPDs may eat baby shrimp, especially if the shrimp are newly hatched. However, they usually leave adult shrimp alone. If you're keeping shrimp, make sure to provide plenty of hiding spaces by using things like Java Moss or botanicals.
