General Description
Barilius Bakeri, commonly known as the "royal danio" or "blue-spotted hill trout," is identifiable by bluish-green spots along its body, white margins on dorsal and anal fins, and fleshy gill rakers. The species belongs to the family Cyprinidae and reaches a maximum size of 13.0cm. Indigenous to the Western Ghats mountains in southwestern India, it thrives in well-oxygenated, fast-flowing rivers with gravel or boulder substrates.
Aquarium Setup
To replicate its natural habitat, a tank for Barilius Bakeri should mimic a flowing stream with rock, sand, and gravel substrate. Incorporating driftwood and hardy plants like Microsorum or Anubias is recommended. Clean water with high oxygen levels is crucial, necessitating external filters and regular water changes. A secure cover is essential due to the species' jumping tendency. The fish thrives in water temperatures of 18-26°C with a pH of 6.0-7.5 and hardness of 18-179ppm.
Behaviour
Barilius Bakeri exhibits gregarious behavior, preferring to shoal in groups of five or more individuals to establish a pecking order. Keeping smaller tankmates is not advised as the species is fast-moving and can intimidate slower companions during feeding times. Suitable companions include robust cyprinids like Dawkinsia and larger Devario species, along with bottom-dwelling varieties such as Garra and Crossocheilus.
Feeding and Diet
In its natural habitat, Barilius Bakeri feeds on aquatic and terrestrial insects, small fish, and benthic invertebrates. In captivity, a diet of quality dried foods supplemented with live or frozen fare like bloodworms, Artemia, earthworms, fruit flies, and crickets will support their health.
Reproduction & Dimorphism
Stimulating spawning in Barilius Bakeri can occur with cool water changes, although raising fry poses challenges. Female fish tend to grow larger and thicker when gravid, displaying subdued colors. Males develop breeding tubercles on the head and orange pigmentation on their lower body during the breeding period.
Habitat and Distribution
Endemic to the Western Ghats mountains in India, Barilius Bakeri inhabits rivers like Periyar, Kabini, and Chittar. Unfortunately, their natural habitats face pollution from industrial waste and invasive species, threatening their survival.
