Origin and Distribution
The ruby barb originates in Sri Lanka, where it was once plentiful in the forest streams in the upper elevations of the Kelani and Niwala river basins. This native habitat is composed of dense vegetation and slow-moving waters, which are colder than many tropical areas. The water in these streams is soft and acidic, and the river beds are composed of sand or fine gravel.
Unfortunately, populations have greatly diminished due to over-catching by those selling these fish for export in the aquarium trade. Rapid deforestation has also eliminated much of the original habitat of these beautiful fish. At one point, they were on the brink of extinction but are currently listed as vulnerable by the International Union for Conservation of Nature (IUCN). Only with proper conservation methods will they remain as a viable population in the wild.
As of 2020, the export of wild-caught ruby barbs from Sri Lanka is prohibited. All specimens sold in the aquarium trade are commercially bred, either in Sri Lanka or in a number of other countries that commercially breed aquarium fish. This commercial breeding has resulted in the creation of a variety of new colors and fin morphs compared with the wild fish.
Colors and Markings
Possessing a pointed head, high back, and deep body, the ruby barb is similar in body type to other banded barbs, such as the tiger barb. Three wide black bands run vertically through the body. In juvenile fish, the body is a pale yellow to yellow-gray. As the fish matures, the head becomes purple-red in color. In males, the entire body assumes this deep red color once they attain breeding age.
Both sexes will pale in color when they are stressed, frightened, or are suffering from a disease or poor care. It is quite common for specimens in pet shops to appear washed out, then regain their bright coloration when taken to a quieter environment in a home aquarium. This species does not have barbels, which are feelers near the mouth or nasal cavity, like other barbs.
