Cichlids are one of the larger categories of ornamental fish. They are distributed almost all over the world, playing the melody of life in different forms. Most cichlids breed their offspring by mouth hatching, in which adult cichlids will suck them into their mouths and wait for them to hatch after laying eggs.
During this time, the adult fish will hide, do not move randomly, do not eat, and even the usually aggressive nature is also converged. In order to hatch the next generation, they often have to endure for more than three days, because they do not eat for several days, the physical state of the cichlid will also be affected, so when the eggs are hatched, the adult's body is the weakest.
The small fry come out of the adult fish's mouth and will always follow the adult fish, at this time the cichlid begins to eat, but the range of activity is still limited. Although the IQ of the fish is not high, the effort it makes for the next generation is not worse than that of other animals. Especially in the dangerous wilderness, if you insist on hatching with your weak body, you must have the consciousness of playing with your life.
In addition to cichlids, Arowana hatches in a mouth-to-mouth manner. If you link these two types of fish, you will find that this seems to be a conventional trend. In order to ensure the continuation of the race, they eventually sacrificed some of their interests. What is obtained is a weak adult fish with a higher hatching rate of fish eggs. The long river of history has drowned countless creatures, and the arowana eventually stumbled and survived, and the reason for this cannot be said to have nothing to do with hatching rate.
