Aquarium-bred Form

Overview

Fish bred in captivity over several generations are better adapted to a wider range of water parameters and more readily accept dry prepared foods.

Appearance

Shared with the species: Gracile Barb

The body is elongated, slender, and moderately compressed laterally, silvery with a golden or yellowish tinge. A characteristic small dark spot is clearly visible at the base of the caudal fin. Fins are transparent or lightly colored, sometimes with a yellowish tinge at the base. Adults reach 6–7 cm in length; males are generally slimmer and slightly more brightly colored than females.

Care

Shared with the species: Gracile Barb

A group of 6–8 individuals requires a tank of at least 80–100 liters. Good filtration and moderate aeration are essential — the species is sensitive to nitrate accumulation and organic waste. Optimal water parameters: temperature 23–26°C, pH 6.5–7.5, hardness up to 12 dGH. A planted tank with open swimming areas in the center is ideal. Weekly water changes of 25–30% are mandatory, and a tight-fitting lid is necessary as these active fish can jump.

Feeding

Shared with the species: Gracile Barb

Omnivorous with a hearty appetite and undemanding about diet composition. The staple consists of quality flakes and micro-pellets. Supplement regularly with live or frozen foods: bloodworms, artemia, daphnia. A plant-based component is important — spirulina-based foods or blanched zucchini and spinach work well.

Compatibility

Shared with the species: Gracile Barb

Peaceful schooling fish that coexist well with other small West African species — Congo tetras, African characins, Kribensis dwarf cichlids. Avoid housing with veiltail or slow-moving fish that may be nipped or harassed. Best suited to West African biotope setups with similarly ranged species.

Breeding

Shared with the species: Gracile Barb

Breeding in captivity is possible but infrequent due to the rarity of this species in the trade. Spawning is triggered by gradually raising the temperature to 26–28°C combined with generous live food feeding. Eggs are scattered among fine-leaved plants or Java moss. Adults must be removed after spawning as they consume eggs. Incubation takes about 24–36 hours; larvae become free-swimming after another 2–3 days, initially feeding on infusoria and artemia nauplii.

Fun facts

Shared with the species: Gracile Barb

The name 'gracilis' comes from Latin meaning 'slender' or 'graceful' — a perfect description for this streamlined fish. The species belongs to the genus Enteromius, one of the largest genera of African freshwater fish, comprising over 200 species. In Russian aquarium hobby, the Gracile Barb remains a rare find, more valued by African biotope collectors than mainstream hobbyists.
