Gold Barb
Barbodes semifasciolatus
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.

Gold Barb Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Gold Barb (Schuberti)
The highly popular golden morph created by Thomas Schubert. Features a bright golden-yellow body with random dark flecks along the lateral line. The absolute standard form in the aquarium trade.
Same care requirements as the base species
Also known as: Schuberti, Golden Barb, Standard
Green Barb (Wild Type)
The natural wild form of the species, featuring a metallic green/olive body with dark vertical bars. Far less common in the trade than the gold morph, but shares identical care requirements.

Gold Barb Care Guide Summary
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.
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.
Who Gold Barb Is Actually For
Gold Barb is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide a keeper who can commit to a proper group of at least 6. It makes the most sense for a hobbyist who will actually build around its needs, especially plants.
The most common mistake is buying Gold Barb for looks first and only later discovering how its adult size, behavior, or bioload changes the whole tank plan. Another frequent problem is underestimating its social needs. A token pair or trio often behaves very differently from a real group.

Fish Similar to Gold Barb
Chinese Barb (Green Barb)
Puntius semifasciolatus
A hardy, active, and peaceful schooling cyprinid originally from the Red River basin in Asia. While the wild form is a metallic green/silver, a highly popular selectively bred yellow morph (the 'Gold Barb') dominates the aquarium trade. They are distinctly subtropical and thrive in unheated or cooler water setups.
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.
Gold Tetra
Hemigrammus rodwayi
A peaceful, active schooling fish perfect for community planted tanks. Fascinatingly, the brilliant metallic gold coloration of wild specimens is a harmless immune response (guanin deposits) to a trematode parasite. Captive-bred specimens lack this parasite and display a silvery-yellow sheen instead. They thrive in mature, dimly lit aquariums with soft water.
Golden Dwarf Barb
Pethia gelius
The Golden Dwarf Barb is a diminutive, peaceful schooling fish native to South Asia. It is often confused in name with the much larger 'Golden Barb' (Barbodes semifasciolatus), but it is a distinct nano species. Due to their small size and slightly timid nature, they do best in heavily planted, peaceful setups and are considered safe to keep with adult dwarf shrimp. They prefer slightly cooler, sub-tropical water temperatures.
Andinoacara sp. Gold Saum
Andinoacara sp. "Gold Saum"
Commonly sold in the aquarium trade as the 'Green Terror', the Gold Saum (technically Andinoacara rivulatus) is a stunning but highly aggressive Neotropical cichlid. Males develop magnificent iridescent scales, orange/gold-edged fins, and a pronounced nuchal hump. Due to their territorial nature and large adult size, they are best kept as solitary centerpiece fish or with highly robust, similarly-sized tank mates. They are avid diggers and will uproot or destroy most live plants.
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.
