— Rasbora reticulata — Rasbora reticulata [Weber & De Beaufort, 1915]. Synonym: Rasbora reticulatus. Indonesia, Sumatra Island. 6 cm. It has a high, strongly laterally compressed body and a slim caudal peduncle. Head is small, eyes are large. Caudal fin is bilobed. Males have a reddish-bronze coloration, while females are yellowish-silver. A dark crescent-shaped border runs along each scale, making the fish look mottled. Males are slimmer, females are larger, yellowish-silver in color, with a more rounded belly line.
Peaceful, schooling, very active, requiring sufficient swimming space. Aquarium should feature various shelters and plant thickets in the background. Lighting should be diffused. It is best to keep them in a school of 5-7 individuals. Keeps to the middle and upper water layers. Non-aggressive fish should be chosen as tankmates. Gets along well with other similarly peaceful, active fish.
To create optimal maintenance conditions, aeration and powerful filtration, diffused lighting, and regular water changes are required. Eats live (small bloodworms and crustaceans), frozen, and dry food. Adults are prone to chilodonelliasis. Reach maturity after six months. Lifespan up to 5 years. pH 6-7; dH up to 10°; T 22-26°C.
— Red-finned Rasbora — Rasbora rubrodorsalis [Donoso–Buchner & Schmidt, 1997]. Mekong River basin. Inhabits slow-flowing waters, ditches, and shallow ponds. 3.5 cm. Body is silver-blue with bright red spots at the base of the dorsal and caudal fins. A narrow black stripe runs along the middle of the body from the front edge of the gill cover to the base of the caudal fin, and above it a second pale yellow iridescent stripe. In youth, this stripe is faintly noticeable. The reticulated scale structure is clearly visible. Anal and paired fins are transparent. Turns very pale when frightened.
Aquarium with dense vegetation and floating plants. They should be kept in a school of 6 or more individuals with calm fish. Males may fight for dominance over a female. Does not like strong fluctuations in water parameters; infrequent regular water changes are needed, as they prefer “old” water. They eat flakes and pellet food, but live food must be given at least two to three times a week. Lifespan 6 years. pH 6.0-7.5; dH up to 10°; T 23-27°C.
— Sarawak Rasbora — Rasbora sarawakensis [Brittan, 1951]. (Eng. Sarawak Rasbora). Malaysia, Indonesia, Borneo. 4 cm. Coloration is beige with a greenish tint and blue-pink lines along the body. Belly is silvery, fins are orange. Male is brighter, smaller, and slimmer. Peaceful, active. These fish can only be kept in a large school, in a densely planted and elongated aquarium with plenty of swimming space in soft water. Partial light dimming with floating plants.
— Steiner’s Rasbora, Chinese Rasbora — Rasbora steineri [Nichols & Pope, 1927]. Synonym: Rasbora volzi pallopinna. (Eng. Chinese Rasbora, Gold Line Rasbora). Laos, Vietnam, southern provinces of China, Hainan Island. 7 cm. Main coloration is silver-yellow, with a golden stripe running along the body above a velvety black stripe. Tail is bright red. Males are more miniature than females. Peaceful schooling fish. In the aquarium, they get along well with other fish, forming mixed schools with closely related species. Mature at 6-8 months. Lifespan up to 6 years. dH up to 12°; pH 6.2-7.2; T 23-25°C.
