Barbodes semifasciolatus
The wild form is green-brown, but the xanthic strain in the trade is golden all over, with a row of short black marks along the flank. A hardy barb that tolerates cool water and settles in groups of five or more.
Barbodes semifasciolatus ranges from the Red River basin across southern China to Hainan. FishBase records a maximum of 7.6cm TL, a common length of 3.5cm, pH 6.0-8.0, 5-19 dH, 18-24C and depths of 5m or less, with a diet of worms, crustaceans, insects, plant matter and detritus. Seriously Fish gives 75mm SL, 16-24C, pH 6.0-8.0, 2-20 dGH and a 90 x 30cm base of about 81 litres. The wild fish is green-brown above with metallic green-yellow flanks, but the fish sold in the hobby is a xanthic captive strain that looks gold all over. Four to seven short black marks run along the flank, and breeding males flush yellow-green on the belly. Being subtropical it takes cooler water well and should not be kept warm year round. Spawning takes place in the early morning. The IUCN rates it Least Concern and it is not listed by CITES.

Seriously Fish suggests a 90 x 30cm base of about 81 litres and FishBase a minimum tank length of 60cm. It is an active swimmer, so keep the front open and plant the back for better colour.
Seriously Fish gives 16-24C, pH 6.0-8.0 and 2-20 dGH; FishBase records 18-24C. As a subtropical fish it handles cool water well, and keeping it above 28C year round shortens its life.
Peaceful and easy to combine with similar-sized open-water cyprinids and loaches. Because it prefers cooler water, avoid species that need high temperatures. A group of five or more settles it.
An omnivore taking worms, crustaceans, insects, plant matter and detritus. It feeds readily on dried food, and combining a plant-based food with frozen fare keeps colour and condition.
An egg scatterer with no parental care; FishBase notes that spawning takes place in the early morning. Females are plainer and thicker-bodied than males, so sexing is easy. Spawn them in a separate tank over mesh the eggs can fall through.
Hardy and disease-resistant, but poorly suited to long spells at high temperature. Almost all traded fish are the xanthic strain, and the green-brown wild form is rarely seen. The IUCN rates it Least Concern and it is not listed by CITES. In English, Pethia gelius is also called the golden barb, so match overseas care information against the scientific name Barbodes semifasciolatus.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Golden Barb is 16〜24℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Golden Barb is 4-7 years. With proper care and nutrition, they can live a long and healthy life.
Golden Barb typically reaches Up to 7.6cm TL as an adult. Size may vary depending on care conditions and individual genetics.
Golden Barb feeds on: Dried, frozen and live foods. Aim for a balanced diet with appropriate feeding frequency.
