The black ruby barb or purplehead barb is a tropical cyprinid fish endemic to Sri Lanka, where it occurs in forested streams from the Kelani basin to the Nilwala basin. They are found in streams on hills around 1000 ft in elevation. The brightly colored population introduced to Mahaweli at Ginigathena, Sri Lanka, is said to have diminished in number due to the aquarium export trade.
The giant danio is a tropical fish belonging to the minnow family Cyprinidae. Originating in Sri Lanka, Nepal, and the west coast of India, this species grows to a maximum length of 4-6 inches (10-15 cm), making it one of the largest of the danionins. It is characterized by a blue and yellow, torpedo-shaped body with gray and clear fins.
Devario is a genus of fish in the family Cyprinidae native to the rivers and streams of South and Southeast Asia. These fishes have short barbels and many species having vertical or horizontal stripes. These species consume various small, aquatic insects, crustaceans and worms, as well as, in the case of fry, plankton.
The barred danio is a fish belonging to the minnow family (Cyprinidae). Originating in Sri Lanka, this fish grows to a maximum length of 2 inches (6 cm).
Danio is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia, commonly kept in aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbels. Species of this genus consume various small aquatic insects, crustaceans and worms.
The green labeo or mountain labeo, is a species of freshwater fish in the family Cyprinidae. It is found only in Sri Lanka, where it occurs in streams in the basin of the Mahaweli River.

Pethia cumingii, known as the Cuming's barb or the two spot barb, is a species of cyprinid fish endemic to Sri Lanka.
Puntius kelumi is a species of cyprinid fish in the genus Puntius. It is found in Sri Lanka.
The horadandia, green carplet, or glowlight carplet, is a species of very small cyprinid fish that is found in slow-moving or still fresh and brackish water habitats in western Sri Lanka. Earlier thought to be a monotypic genus with the single species found in both Sri Lanka and India, an analysis published in 2013 showed that the Indian population should be recognized as a separate species, Horadandia brittani.
The danionins are a group of small, minnow-type fish belonging to the family Cyprinidae. Members of this group are mostly in the genera Danio, Devario, and Rasbora. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. Danio species tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels. Devario species tend to have vertical or horizontal bars, and short, rudimentary barbels, if present at all. All danionins are egg scatterers, and breed in the rainy season in the wild. They are carnivores, living on insects and small crustaceans.
