The tinfoil barb is an active, peaceful species that spends most of its time in the mid-level and bottom of the water. The tank should be decorated with driftwood branches, water-worn rocks of varying sizes and aquatic plants such as Java Fern, Bolbitis or Anubias species for aesthetic value. The Tinfoil Barb is an active jumper, so a tight-fitting hood is required to prevent injury. The tinfoil barb also requires heavy feeding so good filtration system is required to keep water quality within acceptable parameters. 25 – 50% of the tank water should be replaced at least once a month. If the tank is densely stocked 20 – 25% should be replaced weekly or every other week.
The tinfoil barb is omnivore species and in wild condition, its natural diet consists largely of aquatic macrophytes and submerged plants including filamentous algae. In captive condition it accepts most prepared commercial fish foods including flakes, pellets, frozen, freeze dried foods. It also takes live food such as Tubifex worms, brine shrimp and small fish.
The tinfoil barbs is an egg scattering species. They are not often bred in captivity due to their large size. The female can produce several thousands of eggs during one spawning. It prefers higher temperatures during breeding season which ranges from 77 – 80° F. After releasing eggs adults should be removed from the tank to protect them from eating the eggs. The transparent eggs hatch in about 24 hours at a temperature of 75° F. In about six days the young are free-swimming and can be fed with infusoria, a liquid fry food, or newly hatched baby brine shrimp until large enough to accept crushed flake food. Feed should be offered at least three times a day. The fry always require clean water to survive.
Sexing the tinfoil barb is very hard. There are no external differences between male and female. Mature females are usually deeper-bodied than males especially during spawning season. Otherwise there are no obvious external differences.
