Breeding

This must be extremely densely overgrown. Moss and fine other plants are best suited. The tank does not need light or a filter. As soon as the mating process is finished, i.e. the male fertilizes the eggs of the female, the parents should be removed from the aquarium. Otherwise, they may eat the eggs.

Keeping calestial pearl danios

Calestial pearl danios are easy to care for animals. To keep a group of 10 specimens, an aquarium size of 60l is recommended. However, keeping about 6 animals in a 30l tank can also be successful. However, the setup and other characteristics must be exactly adapted to these animals. Therefore a dark substrate and strong planting is recommended to imitate their natural habitat. Also floating plants with long roots or furnishings such as wood or stones, which create a hiding place, are helpful. With the filter, it should be noted that it does not cause too strong a current, otherwise the fish could hide. Feeding can be done with simple granules, which sink to the bottom. Food that floats on the surface, these fish often do not accept.
