Family: Cyprinidae
Distribution: Puntius filamentosus, better known as Blackspot Barb, is a south Asian freshwater species endemic to India, where it is distributed in lowland rivers, estuaries, reservoirs, clear streams, ponds and lakes.
PH: 6.0 – 6.5
Temperature: 20°C – 24C (68 – 75F)
Hardness: 5 – 10 dH
Description: While Puntius filamentosus can reach a maximum length of 18 cm, its common length is around 11 cm. This species has a typical barb shape, large green-blue – often silver – scales, and a large spot on its flanks near the tail. The tail is a distinctive scissor-shape with black and red tips. Blackspot Barbs are tough to sex when young, but adult males are more colourful than females and have a less rounded belly and extended filaments to their dorsal fin rays.
Diet: Puntius filamentosus, an omnivore, will eat most foods. In an aquarium environment, you should feed this species regular meals of live and frozen foods – bloodworm, Daphnia and Artemia – along with quality flakes and granules. Quality live foods will bring out a bright, dazzling colouration.
Breeding: This species will require a dimly-lit tank and fine-leaved plants or a spawning mop, along with a slow-moving current. Puntius filamentosus will spawn at daybreak and will eat the eggs if given the chance; you should remove the parents as soon as you see eggs in your tank. The fry will hatch in 24 – 48 hours and can be fed on Infusoria before moving on to freshly hatched brine shrimp.
Comments: You should tank this species in a tank with a capacity of at least 108 litres, even larger if possible. The Blackspot Barb will need good lighting and a dark substrate in order to show its best colours, and must be kept in well-oxygenated waters. Decorate your tank with smooth rocks, live plants and twisted roots. This active species is suitable for beginners.
