General Description:
Barilius Canarensis is a species historically linked with B. ardens and B. malabaricus in the aquarium trade, distinguished by its unique color pattern, broad white margins on fins, and slender gill rakers. The genus Barilius has had a complex taxonomic history, with some species reclassified into Opsarius. The fish thrives in well-oxygenated, fast-flowing rivers with gravel and rock substrates.
Aquarium Setup:
For Barilius Canarensis, a tank mimicking a river ecosystem is crucial, with gravel, sand, boulders, and driftwood. Hardy plants such as Microsorum can be added, but the focus should be on ample swimming space. Clean water, high oxygen levels, and moderate water movement are vital, necessitating filters and regular water changes. Due to their jumping tendency, a secure lid is essential.
Behaviour:
Barilius Canarensis is unsuitable for community tanks due to its fast-swimming nature and bold feeding behavior, which may intimidate slower or smaller tankmates. This shoaling species requires a group of five or more individuals to establish a pecking order and prevent aggression among group members.
Feeding and Diet:
In the wild, Barilius species are surface-feeders consuming insects, small fish, and invertebrates. In captivity, they accept dried foods but thrive on live or frozen fare like bloodworms, Artemia, and chopped earthworms. Gut-loaded fruit flies and crickets can also be offered for a varied diet.
Reproduction & Dimorphism:
Breeding Barilius Canarensis may be induced by cool water changes, although fry rearing reports are scarce. Adult females are larger and less brightly colored than males, with gravid females exhibiting a thicker body. Males develop breeding tubercles and orange pigmentation during the breeding season.
Habitat and Distribution:
The species is primarily found in southern Karnataka and northern Kerala states in India, particularly in the Netravathi and Tungabhadra river systems. Barilius Canarensis inhabits fast-flowing rivers polluted by domestic and industrial waste, facing threats from invasive species and sand mining. Sympatric species include various fish and bottom-dwellers in its native habitats.
