General Description
Brachydanio Tinwini, commonly known as the Gold Ring 'Danio,' is a small species of fish belonging to the Cyprinidae family. It was first introduced to the aquarium trade in the early 2000s and is distinguishable by its spotted patterning in the unpaired fins and smaller size compared to related species.
Aquarium Setup
To create an ideal habitat for Brachydanio Tinwini, it is recommended to maintain them in a well-planted tank or an environment resembling a flowing river. The setup should include a dark substrate, variably-sized rocks, gravel, water-worn boulders, and driftwood. Hardy aquatic plants like Microsorum, Bolbitis, or Anubias can be added, while a tightly-fitting cover is essential due to their jumping ability. Providing calmer water conditions is preferable, avoiding strong currents.
Behaviour
Known for their peaceful nature, Brachydanio Tinwini thrives in community tanks with other compatible fish species. They are schooling fish by nature and should be kept in groups of at least 8-10 individuals. Maintaining them in decent numbers reduces stress, enhances natural behaviors, and brings out the best colors in males during breeding displays.
Feeding and Diet
As omnivores, these danios primarily feed on insects and larvae in the wild. In captivity, they accept a variety of foods including high-quality dried products as a staple diet. Supplementation with small live and frozen foods like bloodworms, Daphnia, and Artemia enhances their coloration and overall health.
Reproduction & Dimorphism
Brachydanio Tinwini are egg-scattering spawners that exhibit no parental care. To encourage breeding, a well-conditioned group can be introduced to separate breeding containers with soft, slightly acidic water and dim lighting. Sexually mature females are typically larger and rounder-bellied than males. After spawning, adults should be removed to prevent egg predation.
Habitat and Distribution
Endemic to the Mogaung Chaung in northern Myanmar, Brachydanio Tinwini inhabits slower-moving, oxygen-rich streams in the Kachin State. The species is part of Myanmar's diverse fish fauna, mostly comprising endemic species within the country's water systems.
