The Moustached Danio, scientifically known as Danio dangila, is a fascinating and attractive species of fish native to the fast-flowing streams and rivers of South Asia, including parts of India, Nepal, and Myanmar. This species is distinguished by its larger size compared to other Danio species and the characteristic barbels or "moustaches" that extend from its mouth, which are particularly prominent in adult specimens.

Danio dangila typically displays a slender, elongated body with a silver base color accented by one or more horizontal blue stripes running the length of the body. The fins are often translucent and can have a hint of yellow or orange, especially in males during breeding conditions. This striking coloration, combined with their active swimming behavior, makes them a lively addition to the community aquarium.

In the aquarium, Moustached Danios thrive in conditions that mimic their natural riverine habitats. This includes setting up a tank with ample swimming space and a current to simulate flowing water. They are schooling fish and should be kept in groups to encourage natural behavior and reduce stress. The presence of fine-leaved plants, rocks, and driftwood not only adds to the aesthetic appeal of the tank but also provides hiding spots and breaks the flow of water, creating a more dynamic environment.

The water quality for Moustached Danios needs to be maintained at high standards, with regular water changes to keep the parameters stable and the environment clean. They prefer cooler water temperatures and clean, well-oxygenated water, making them somewhat more challenging to keep than other tropical species that thrive in warmer conditions.

Diet-wise, Danio dangila is omnivorous and not particularly picky. They do well on a diet of high-quality flake food, supplemented with small live or frozen foods such as daphnia, brine shrimp, and bloodworms. These additional protein sources help maintain their health and vitality, and the varied diet also encourages more vibrant coloration.

Breeding Moustached Danios can be a rewarding experience, as they are egg scatterers, typically spawning in the early morning. Fine-leaved plants or spawning mops can be used to catch the eggs, as adults do not exhibit parental care and may eat their eggs if given the opportunity. The water should be slightly cooler and cleaner than usual to simulate the onset of the monsoon season, which naturally triggers spawning.

While the Moustached Danio is not considered endangered, habitat destruction and pollution in their native regions pose potential threats to their populations. Sustainable practices and conservation efforts are important to ensure their survival in the wild.

Overall, the Moustached Danio offers an appealing mix of beauty, intriguing behavior, and a moderate care level, making it suitable for aquarists who are looking for something a little different from the typical offerings in the danio family. Their playful nature and striking appearance can significantly enhance the dynamics of a community tank.
