Why fish farming easily die?
There are many reasons why the aquarium fish cannot grow healthy and even die. In particular, the main causes include environmental, air, too small aquarium size or too many fish.
Due to the water environment
Fish can not survive if the water environment is alum contaminated, contains lots of chlorine, polluted .... Moreover, the hardness and pH of the water are not suitable for the growth of fish as well as cause the fish to die. Therefore, players need to pay attention to appropriate water treatment.
Due to the air
Air includes both light and temperature. Must provide enough light to beautiful fish, bright colors are. If there is not enough light, the air is too dark, the color of the fish will be pale and the fish will die. If the amount of light is too large, shining directly into the tank will cause the water to heat up, causing the fish to get tired and die faster.
Or in the cold season, in the northern regions, the temperature decreases rapidly, if not equal to the water temperature in the aquarium, the fish will die. Because most of the ornamental fish in our country are tropical fish, they cannot survive in cold water.
