After the female fish of the colorful angelfish ovulates, the male fish will automatically fertilize the eggs under normal circumstances, so the fertilized live eggs are generally not epiphytic. Only eggs that die unexpectedly after fertilization will be epiphyte. And only in the case of a large number of water mold in the aquarium, the normal fertilized eggs will be harmed by water mold. Therefore, under the condition that the water quality in the aquarium is stable and good, it is not necessary to carry out anti-mildew treatment for those normally fertilized eggs. Only for those eggs with poor fertilization rate, drug mildew treatment will make some sense.

In order to avoid the parent fish from swallowing the eggs when the colorful angelfish hatches With newly hatched juveniles, it is very necessary to use a sleeve or metal cover. However, when using the sleeve tank, it should be noted that the amount of water in the sleeve tank is very small, and the water quality is easy to deteriorate, especially the content of ammonia nitrogen and nitrite will significantly exceed the content in the water body of the broodstock tank.
