Breeding and reproduction

The breeding and reproduction process is a vital aspect of the lifecycle of any species. It plays a fundamental role in maintaining population numbers and ensuring the survival of the species. In the case of Brevibora dorsiocellata, also known as the celestial pearl danio or galaxy rasbora, the breeding and reproduction process is both intricate and fascinating.

During the breeding season, which typically occurs in the spring and summer months, the celestial pearl danios engage in elaborate courtship displays. Males will showcase their vibrant colors and patterns while performing various fin displays to attract females. They will often chase the females in a spirited manner, and the females, in turn, assess the males’ qualities to choose a suitable mate.

Once a mating pair is established, the female scatters her eggs, and the male swiftly fertilizes them. The eggs are adhesive and will typically attach to plants and other surfaces within the aquarium. The celestial pearl danio is an egg-scattering species, which means that it does not provide parental care for its eggs or offspring. After the fertilization process is complete, it is crucial to remove the adults from the breeding tank to prevent them from consuming the eggs.

The eggs of Brevibora dorsiocellata hatch within 24 to 36 hours, depending on water temperature and other environmental factors. The newly hatched fry are incredibly tiny and transparent, making them quite challenging to spot. At this stage, they rely on their yolk sac for nutrition.
