How about koi? how to understand the health status of fish?

The health of fish should be carefully observed before deciding to buy, because unhealthy fish are often the cause of disease transmission in the aquarium later, which is extremely destructive for an aquarium which is already in stable condition.

Henan ornamental fish culture base reminds you that before purchasing, you should consider:

1. The health of fish-whether they are lively and behaving normally.

two。 The compatibility between new fish and other fish-whether there will be fights or cannibalism.

3. Breeding space-whether there is enough remaining aquarium space to accommodate new fish to fully mature. When the new fish can meet the above conditions, the purchase decision can be made formally.

The observation of the state of the fish itself directly affects the interest of breeding, and only the fish with healthy and normal color can be favored by the breeders themselves. The body surface of healthy fish should be smooth, at the same time, the secretion of body surface mucosa should be normal, and each fin should be transparent and bright; generally speaking, in healthy fish, the eyes (eye mask) should be clear and free of dirt; nostrils, Gill tissue, fins and anus should not be congested or other abnormal conditions. Therefore, when fish lack the above conditions, the breeders themselves should find out the factors that affect the occurrence of this situation and improve it quickly. And observing the status of fish and fish or fish and surrounding breeding environment should also be the focus of observation. Do fish attack each other or repel each other? Or the poor growth of only some of the fish. All the problems must be carefully observed by the breeders themselves before a conclusion can be drawn.

In addition, such as regular water change, regular water quality testing, etc., are also necessary for a responsible aquarium enthusiast, especially for some aquarium enthusiasts engaged in breeding or breeding, the concept of "feeding process" is even more important!
