Ruby barbs are omnivorous, they will accept flakes and pellets, a treat of blood worms and brine shrimp should be given at least once a week.


Ruby barbs originate from Sri Lanka where they occupy the basins of the rivers and in the hilly streams.


The males tend to be more colored than the females but with a darker background. They will also have a hint of red on their anal and pelvic fins.


Plants should be provided in the breeding tank, if not a spawning mop should be added. The Ruby Barb is an egg scatterer and the parents will eat the eggs if given the chance. After spawning is complete, remove the parents, the eggs should hatch after 24 hours. The fry will become free swimming several days later.


The average lifespan for Puntius nigrofasciatus is 5 years.
