A highly active, peaceful schooling fish. The common 'Gold' variant is a captive-bred color morph (Schuberti) of the wild Green Barb. They are remarkably hardy and prefer slightly cooler sub-tropical water, making them excellent candidates for unheated indoor aquariums.

The Gold Barb, scientifically known as Barbodes semifasciolatus, belongs to the Cyprinids family group. Adults reach a maximum size of approximately 7.5 cm and have a fusiform body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a low level of biological waste.
To thrive, the Gold Barb requires a freshwater only aquarium with a minimum volume of 75 litres and a tank length of at least 60 cm. Water temperature should be maintained between 16°C and 24°C, with a pH range of 6–8 and a general hardness of 2–20 dGH. A moderate water flow is preferred. An aquarium test kit can help you monitor these values.
The Gold Barb is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Gold Barb (Schuberti) and Green Barb (Wild Type). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Gold Barb Habitat Setup
When setting up an aquarium for the Gold Barb, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include dense planting to provide cover, break sightlines, and reduce stress.
Gold Barb Compatibility Notes
Classified as peaceful, the Gold Barb is a schooling species that feels most secure in a sizeable group, where natural shoaling behaviour reduces stress and brings out their best colours. When choosing tankmates, their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Similar Species
Rosy Barb
Pethia conchonius
A hardy, active, and colorful subtropical schooling fish. Known for the male's striking rosy-red breeding dress, while females are more golden/silver. They are voracious eaters, very active swimmers, and can be fin-nippers if kept in too small a group. Best kept in cooler water compared to tropical species. The Long Finned morph is also popular but requires gentler flow.
Tinfoil Barb
Barbonymus schwanenfeldii
A large, active, and schooling riverine species that quickly outgrows standard aquariums. Known for their metallic silver scales and red fins. They are notoriously skittish, robust eaters, and will consume almost any live plant or small fish that fits in their mouths. A massive tank with strong filtration is strictly required.
Goldfish (Comet / Common)
Carassius auratus
One of the most commonly kept and misunderstood fish in the hobby. Single-tailed goldfish (Comets, Commons, Shubunkins) are fast-growing, highly active coldwater fish that produce enormous amounts of waste. They are best suited for ponds or massive aquariums. They will uproot plants, sift substrate constantly, and eat anything that fits in their mouths.
Odessa Barb
Pethia padamya
A highly active, stunning schooling fish known for the brilliant red lateral stripe running across the males. Originating from central Myanmar, they thrive in slightly cooler, sub-tropical water compared to typical tropical fish. They are robust and peaceful when kept in proper shoals, but may nip fins if stressed or kept in numbers too small.
Cherry Barb
Puntius titteya
A peaceful, schooling cyprinid endemic to the shaded streams of Sri Lanka. Unlike many of its barb cousins, the Cherry Barb is not a fin-nipper and makes an excellent community fish. They thrive in heavily planted aquariums with subdued lighting and leaf litter. Males display a striking cherry-red color, especially during spawning.
Tiger Barb
Puntigrus tetrazona
A highly active, schooling cyprinid famous for its striking black stripes and infamous reputation as a fin-nipper. They are boisterous and must be kept in larger groups (6+) to keep their pecking order internal. They should never be housed with slow-moving or long-finned tankmates like Bettas, Guppies, or Angelfish.
