This kind of fish usually needs isolation after spawning. Although it has the characteristics of protecting eggs, they will not eat normal fertilized eggs except those that are white and moldy, so there is no need to worry about hurting eggs. However, the process of taking small fish is tiring, which is not good for the growth of parent fish. It is best to raise them alone.
Skills of male and female separation of swallowfish
Swallow fish is also called angelfish. Both men and women have colors. The mother's belly is bigger, the color is lighter and the fins are not that long. If put together, the fins are not yellow and the body color is cool.
It is difficult to tell the male from the female of angelfish, but they have their own mate selection habits since childhood. Generally speaking, angelfish always swim in the middle water in pairs, with the bigger back and the longer fins being the males. When raising this kind of fish, if it is found that the male and female are intimate, the anus is drooping and protruding, and other angelfish are not allowed to approach, this is a precursor to spawning and reproduction, so it should be picked up in time and put into the spawning box prepared in advance.
Male and female swallowtail fish are not easy to distinguish. Generally speaking, female swallowtail fish are lighter in color and their fins are not as long as those of males. It may be difficult to distinguish this kind of fish at first sight, but you can recognize it when you look closely.
