Pearl Danio (Brachydanio albolineata)

The Pearl Danio (Brachydanio albolineata) is a captivating fish native to Southeast Asia. Let’s dive into some interesting details about this aquatic gem:

• Distribution:

  • Pearl Danios are widely distributed across parts of Myanmar, Thailand, Laos, Cambodia, Vietnam, Peninsular Malaysia, and the Indonesian island of Sumatra.
  • They inhabit various habitats, from well-oxygenated, clear streams with rocky substrates in forested areas to still bodies of water like ponds, ditches, and rice paddies.

• Appearance:

  • These energetic fish grow to a maximum length of 50–55 mm (approximately 2–2.2 inches).
  • Their bodies shimmer with delicate pastel shades of pink, blue, and green, resembling mother-of-pearl.
  • Pearl Danios exhibit two light yellow-white or blue-red stripes along their bodies.

• Aquarium Care:

  • For a thriving Pearl Danio, consider the following:
    • Tank Size: A minimum base dimension of 90 × 30 cm is recommended.
    • Substrate and Decor: A heavily planted aquarium with a darker substrate works well. Large water-worn boulders and variably-sized rocks create a natural river/stream-like environment.
    • Water Flow: Aim for a filter with a water flow between 4–5 times the aquarium volume.
    • Avoid Torrent-Like Conditions: Danionins prefer calmer stretches and marginal zones in nature.
