Egg laying fish such as these barbs do not become gravid ('pregnant') in the way that you would think of in reference to livebearing fish, as fertilization and subsequent development occur outside of the fishes' bodies. They are egg scatterers, meaning that during mating, the female will scatter her eggs in various places in the tank, and the male will follow her, fertilizing them. They do not exhibit any parental care whatsoever and will be just as happy to eat their own eggs as to scatter and fertilize them.
