The tinfoil barb (Barbonymus schwanenfeldii) is a very large fish from Cyprinidae family. It can be up to 14 inches (35 cm) long. Quite often the juveniles are sold on the market and nobody tells about how large the fish becomes as an adult one and as a result, the fish quickly overgrows any tank of a common aquarist and then requires a really spacious tank.
Maximum size: 35cm
Origin: South America
Ideal number kept together: 3+
Hardness: 143-536 ppm
Temperature: 22–25 °C
Ease of care
Keeping such large fish is quite a troublesome and expensive thing to do, that’s why they are quite seldom seen in home aquaria, though in general tinfoil barb is very undemanding. However, the fish has far more strict requirements to tank water quality. Since tinfoil barb habitat is in clean oxygen-rich lotic waters, it can’t stand any organic waste accumulation in water.
The food we recommend is tropical fish flake or a tropical pellet.
In general this fish species isn’t aggressive, but at that it treats all smaller sized tankmates as food.
Breeding / Sex
There are almost no differences between the males and females appearance. Only during their spawning period you may recognize the female due to its rounded abdomen with eggs. Mating season starts when environmental conditions change due to the beginning of rain season and further migration of the fish to flooded areas of tropical forests.
They can live to anything from 10+ years in perfect conditions.
