Generally, do not turn on the light when a new fish enters the tank. Suddenly turning on the light will frighten the fish. Some timid fish may even have a stress reaction, leading to their death. Usually it takes about three days for the fish to adapt to the environment, and then they can try to feed it to see if it eats or not, and if it eats, it means that there is no problem.
1. Rest for a few days: After the new fish enters the tank, it needs to rest for a period of time. Due to changes in the environment, the fish need to adapt. During this period, it must maintain the water temperature to avoid fluctuations in water quality. At the same time, do not feed it. During the adaptation period, the fish's appetite is not strong, they do not eat anything, and the residual bait remains in the tank, which will lead to the deterioration of water quality.
2. Feeding: After the new fish adapts to the environment of the fish tank, it can be fed with feed. According to the different types of fish, its feeding habits are not the same, most of the fish can eat artificial feed, but also some need to feed live bait, such as fish and insects. Proper disinfection is needed before feeding, so as not to make the fish sick.
3. Pay attention to changing water: It is necessary to change water regularly for fish farming. The interval of changing water is mainly determined by the speed of water quality change. If the water quality deteriorates quickly, the water should be changed appropriately. On the contrary, as long as the water body can be kept clear, the time of changing water can be postponed. The amount of water should not be too large, otherwise it will stimulate the fish, generally in a quarter of the total amount of water can be.
