General Description
The Brachydanio Sp. 'Tw01,' commonly known as the Black-Barred 'Danio,' is a species classified under the order Cypriniformes. It exhibits unique body patterning with distinguishing characteristics, such as a dark marking on the caudal peduncle. This species is gregarious by nature, forming shoals and displaying vigorous feeding behavior.
Aquarium Setup
Ideal for larger tanks, the Black-Barred 'Danio' should be housed with robust, similarly-sized fish due to its constant activity. It thrives in a well-planted aquarium resembling a flowing river, with dark substrate, variably-sized rocks, and gravel. Providing hiding spots with driftwood, aquatic plants, and boulders is recommended.
Behaviour
Though not aggressive, the Black-Barred 'Danio' may disturb slow-moving or timid tankmates with its active nature. It is a shoaling fish that forms tight groups when threatened and exhibits male rivalry within the shoal. Maintaining them in groups of 10 or more helps in distributing aggression, with dominant males showcasing more intense coloration.
Feeding and Diet
In the wild, this species likely preys on insects and larvae. In the aquarium, it is an unfussy eater accepting most foods. A varied diet including quality dried foods and live or frozen fare like bloodworms and Daphnia enhances their coloration and overall health.
Reproduction & Dimorphism
The Black-Barred 'Danio' is an egg-scattering spawner without parental care. To increase fry yield, a controlled breeding setup with suitable spawning media and optimal water conditions is recommended. Mature males are more colorful and slim with orange edges on fins, while females have white edges.
Habitat and Distribution
Endemic to western Myanmar near the town of Gwa in Rakhine State, the Black-Barred 'Danio' inhabits tropical monsoon regions. It thrives in streams that swell during the rainy season and flow rapidly. Myanmar is a biodiversity hotspot for the genus Danio, with various species found in the region.
