Observation can pick out some problems. If you just shake your head and don't move when swimming in the water, it proves that you are malnourished, tired when swimming, your abdomen can't bulge, and you have fish lean meat disease. It is found that no matter how beautiful the color is, it is not a high-quality fish, which means that it is sick and unhealthy. If you don't pay attention to it, there will be a situation where the head and tail are uneven, such as the fish's tail is uneven and the long tail is crooked: the eyeball size is not up to standard, and the two balls of the fluffy fish must be symmetrical.

Second, the colors of fish are colorful and dazzling, so we should pay attention to choosing black varieties instead of gray or black-gray varieties: crimson varieties should not be red, yellow or yellow varieties; Some red fish, like carrots, are the least ideal. Some fish are half red and half black, or red with black fins. It looks beautiful, but it's not, because it will turn red soon, so you should have foresight.

There are many kinds of fish in the market, and if you are not careful, you will enter the misunderstanding.

After hatching, Siguan fish has to go through many steps to grow into young fish. In the process of treatment, it is inevitable that some scales are easy to tear and fall off. When fishing, back scales, tail scales and fins are easy to break, and scales on both sides of the abdomen are also easy to fall off. What is particularly prominent is that after the scales of red and black fish fall off, the fish will show gray skin, which is very unsightly and affects viewing.
