The survival rate of the fry is quite high, with almost all of them reaching adulthood. It will not take them long to grow up and rejoin their parents, estimates suggest that they will be ready to join their parents after only a couple of months. The owner will be required to start giving them micro food to keep them well fed. Once out of the egg, the fry will be in a sedentary phase for the first week. Their eggs are temperature sensitive so the number of days after which they hatch depends entirely on the water temperature of your aquarium.Īt around 75-76F they will hatch within 3 days but at temperatures of 70F, they will take 6-7 days to hatch. They will even eat their eggs if they stumble upon them later on, which is why isolation of eggs is required for breeders. It should be noted that Celestial Pearl Danios scatter eggs and do not care much for their maintenance. If the gesture is reciprocated, then the female joins the male in a complex dance after which sperm and eggs are released so they can fuse. Once they have secured a breeding spot among the dense vegetation, they will signal females passing by in groups. How to breed Celestial Pearl Danios and care for the fry?Ĭelestial Pearl Danio males are very competitive, they can easily be observed competing with other males and sporting a bright red mark on their anal fin to signal females. Predatory Catfish (Pectus Catfish, etc.).Smaller predatory fish (African Butterflyfish, Leaf Fish, etc.).Convicts and other aggressive smaller Cichlids.Aggressive Gouramis (Bettas, Paradise Fish).Worst Tank Matesįish to avoid are generally those larger than 4 inches because they consider the Celestial Pearl Danio as food. A rule of thumb is to get tank mates that have almost the same temperature tolerance and other necessary water requirements. It is necessary to consider how much space the new tank mates will occupy and then increase the water volume accordingly. Some of the best tank mates for these micro fish are as follows: If you add bigger fish to the tank, even peaceful ones, they will see it as food and gobble it up.Īdditionally, plump females, help to keep fish that occupy the upper portion of the aquarium so that the Pearl Danios have the bottom portion all to themselves. Tank Mates for Celestial Pearl Danio Best Tank Matesīeing micro-sized, shy and peaceful fish the Celestial Pearl Danio should only be kept in a tank with fish that are the same size and are docile. The owner will need to ensure a clean and healthy environment for the Celestial Danios to ensure reduced stress levels and healthy and colorful fish roaming about in the aquarium. Add food there and they should come out of hiding to feed. The remedy for this is that for active fish, food should be dropped at one side of the tank and when they get busy, the other side should be utilized for shy fish like the Pearl Danios. It should be kept in mind that with aggressive fish in the tank, these shy fish will not be able to receive enough food. If more food was delivered than the Celestial Pearl Danios or other fish can eat then that would result in contamination of the fish tank water. So the solution to this is putting food for the active fish at one end and for the shy fish at the other. Putting all the pellets and other food in the same spot often deprives shy feeders like the Celestial Pearl Danios because once startled, they go into hiding and remain hungry while the other fish finish the food off. When there is a mix of shy and highly active fish in your aquarium, you should keep an eye on them as they feed. A higher-quality spirulina flake can help boost its health as it contains vital nutrients and vitamins. Celestial Pearl Danios also like to feed on live food such as Daphnia, Grindal Worms, and Moina but try to keep a healthy diet with variety because if you keep on feeding them just pellets, it will not fulfill their nutritional requirements.
