Natural habitat

The celestial pearl danio is typically found in freshwater ponds and marshes surrounded by grasslands and rice paddies in Myanmar and northern Thailand. They prefer waters with stable temperatures and quality.

Where they are found

This species is widely distributed across various Asian countries, living in hill stream ecosystems. Its ability to adapt to a range of environmental conditions allows it to thrive in various habitats, although it is often overlooked in aquarist spaces due to its less vibrant presentation in bright environments.

Aquarium care

To maintain their health, keep the water stable with regular changes and provide plenty of vegetation for hiding spaces. They do well in a bigger group (at least six) which promotes their natural behavior.

Feeding

As an omnivore, the pearl danio enjoys a diverse diet, including high-quality flake foods, brine shrimp, and bloodworms. They feed from the surface and mid-levels of the tank, and it’s best to ensure the lid is secure to prevent them from jumping while feeding. Offering live or frozen foods occasionally can enhance their health and may even trigger breeding behavior.

Compatibility

The pearl danio is compatible with a range of small to medium-sized fish. Due to their active nature and social behavior, they should be kept in groups of five or more to reduce stress levels. Avoid slow, timid species as tankmates. The pearl danio works well with various barbs, tetras, loaches, and corydoras.

Breeding

When ready to breed, set up a breeding tank with plants for spawning. The female develops a noticeable spot when ready, and the eggs should be removed post-spawning if you wish to save them.
