Subfamily Rasborinae ( Rasborinae )
Genus Brevibora — Brevibora.
— Brevibora dorsiocellata [Duncker, 1904]. Synonym: Rasbora dorsiocellata. (Eng. Eyespot Rasbora, Emerald Eyed Rasbora, Green Eyed Rasbora, Hi Spot Rasbora). Malay Peninsula, Indonesia, Sumatra. 5-6 cm. Main coloration yellowish-silver with bluish-violet sparkles on the sides. Back brownish, often brownish-olive, belly silvery-white. Distinctive feature: dorsal fin with a coal-black dot spot surrounded by white.
Males are significantly slimmer, caudal fin reddish, females are plumper, tail of females yellowish. In body shape and coloration, it resembles R. taeniata and R. einthoveni. Most frequently encountered subspecies: — R. dorsiocellata macrophthalma up to 3.5 cm. Characterized by brightly glowing blue eyes and a black spot on the dorsal fin.
Peaceful, schooling, keep in groups of 8 or more, active, keeping in a tight school in the upper and middle water layers. Suitable for a community aquarium. Aquarium with hiding places among fine-leaved plants, plenty of swimming space in the front. Does not damage plants. Quite undemanding regarding water quality. Not too hard water is required. Conditions contributing to the accumulation of dissolved organics and oxygen deficiency in the aquarium should be avoided. Decor elements should not be overused, avoiding overcrowding the internal space of the home tank. Omnivorous. pH 6.0-7.0; dH 4-10°; T 20-25°C.
Genus Kottelatia — Kottelatia.
— Kottelatia brittani [Axelrod, 1976]. Synonym: Rasbora brittani. (Eng. Head and Tail Light Rasbora). Malay Peninsula, Johor River, Borneo, Kapuas River. 5 cm. Olive-beige with two rows of brown dots along the spine. At the caudal base, a black spot with a red-orange border. This fish can be easily distinguished from other rasbora species by its more pointed head and intense orange-red spots on the caudal peduncle in front of the caudal fin. Males are slimmer, females are plumper, with a more convex belly line.
Active, peaceful schooling fish. Requires a long aquarium with a dark bottom covered with soft sand, dense vegetation on the sides, and plenty of swimming space. Swims in the upper and middle layers. A cover glass or tightly fitting lid is mandatory as they are expert jumpers. Should be kept only with species requiring similar conditions; cannot compete with large and fast species. Schooling species from 8 individuals, and if kept singly in the aquarium, they become nervous and timid. Water should be soft, neutral or slightly acidic, and as clean as possible. Do not introduce this fish into a biologically immature aquarium, as they are susceptible to fluctuations in water chemistry. pH 6.0-7.0; dH up to 12°; T 22-26°C.
Genus Microrasbora — Microrasbora.
— Microrasbora rubescens [Annandale, 1918]. (Eng. Red Dwarf Rasbora, Red Line Dwarf Rasbora, Flame Red Rasbora, Asian Cardinal Rasbora). Myanmar, Inle Lake, Salween River. 3 cm. Golden-olive with a wide red stripe with a greenish-bluish sheen along the body. Males are smaller and much slimmer. Keep in a school of at least 5-10 individuals. Prefers an aquarium with open space near the surface and dense vegetation on the sides of the aquarium, which can serve as shelter. Keep in a school of 6 or more specimens.
Dominant males conflict with each other and occupy temporarily fixed territories. Young males and females gather in a school, mature females stay near the bottom. Males are especially active in the morning after lights on, courting females with flowing fins. Water flow from filtration should not be strong. Do not introduce into a biologically immature aquarium, as they are susceptible to fluctuations in water chemistry, and be sure to perform regular water changes to maintain quality.
Cannot withstand very high water temperatures for long. Live and dry food should be of small size. May be outcompeted at the feeding area by larger or faster neighbors, although the presence of similarly sized fish will help reduce their shyness. Sexual maturity at 4-5 months. Spawning among fine-leaved vegetation. Live up to 3 years. T 21-25°C; dH up to 15°; pH 6.5-7.5.
Genus Rasbosoma — Rasbosoma.
— Rasbosoma spilocerca [Rainboth & Kottelat, 1987]. Synonym: Rasbora spilocerca. Lower Mekong River basin in Thailand, Laos, and Cambodia, inhabits shallow water bodies and lakes. 3 cm. It is an almost exact miniature copy of the scalloped rasbora (Rasbora trilineata). Body transparent-yellowish with a thin longitudinal black stripe, green above. With a dark spot on the dorsal fin, a dark spot at the end of the tail base, black spots in the middle of the caudal fin lobes, white-yellow stripes below. During spawning, the body of males acquires a pinkish tint, and the fins turn yellow. Males are noticeably smaller and thinner, and generally more intensely colored.
Very peaceful, but not an ideal community fish due to their small size and somewhat timid behavior. Best kept in a large school in a species aquarium with dense planting and floating plants. Males will display their best colors and interesting behavior when competing with each other for the attention of females. Never introduce this fish into a biologically immature aquarium, as they are susceptible to fluctuations in water chemistry. Filtration should not have a strong current, as they originate from sluggish waters. In the aquarium, prefers fine live foods, but will also accept dried products of suitable size. T 22-26°C; pH 6-7; dH 2-10°.
