Chuang tank fish generally put about 5 more appropriate. Because the main function of the fish in the tank is to test the water, if only one is put, it is not easy to determine whether the problem is the water or the fish, put a few more, if only one is sick or dead, it can not explain that the water is not well kept. If many fish enter the tank and die one after another, they need to open the tank again to raise water.
1. Live endurance: The first requirement for rushing into the tank fish is live endurance. If the fish itself is very delicate, once something goes wrong, it is difficult to determine whether the water or the fish is bad. Only fish that are relatively resistant to live skin can be used to prove whether the water quality is suitable for fish farming.
2, easy to raise: Chuang tank fish out of the tolerance to live, but also easy to raise. Because beginners often have little experience in feeding and changing water, it is easy to feed too much, and it is easy to get gastroenteritis when they feed too much fish, so it is impossible to judge whether there is a problem with the water. Similarly, if the water is not changed in time, the deterioration of the water quality will also affect the health of the fish, and the better fish do not require high water quality, so naturally they will not die.
3. No disease: The most important thing about running a fish in a tank is that it is not sick. If the fish are sick at the beginning, if the fish die, it is not easy to say whether it is a disease or a water problem, and the sick fish will pollute the water quality, causing other fish to get sick, and the original good water will go bad.
