When rat fish breeding, we need to do some preparatory work. One of the most important tools is a separate tank, which can be used to place parent fish and let them breed in it. Then there are some other devices. For example, when laying eggs and breeding, we need to ensure the water temperature, sometimes we need heating rods; Moreover, it is necessary to ensure the oxygen content in the fish tank, and sometimes oxygen pumps and other tools are needed. However, these tools are not necessarily used, and can be prepared in advance just in case. In addition, when sucking fish eggs, straws need to be prepared.
Rat fish reproduction, first of all to do the above preparations. Then there is the choice of broodstock, with males outnumbering females. There are many criteria for choosing parent fish, and those who are healthy, moderate in size, appropriate in age and beautiful in appearance are suitable. After selecting them, you need to put them in a separate tank.
Then they go through the process of reproduction. Specifically, called "T-breeding" method, the mother fish will accept the male fish, they will secrete semen in their mouth. After that, the mother fish will lay eggs and spit out the semen, and the eggs will be inseminated. After fertilization, the eggs need to be sucked out with a straw, and the fertilized eggs are hatched separately. It is suitable to adjust the water temperature to 24-26 degrees. After three or four days, they can hatch successfully. At first, the small fish do not need to be fed, and then they can slowly feed some egg yolk and other foods.
