although goldfish can adapt to a large range of water temperature, it is difficult to adapt to sudden fluctuations in water temperature. At this time, the goldfish will not like to swim and refuse to eat, which can cause the death of the goldfish. This situation requires the breeder to pay more attention to ensuring the stability of the water temperature in the fish tank in peacetime.
When the living environment of goldfish changes greatly, goldfish will not adapt to it and sink to the bottom of the water. This phenomenon may occur when the water is changed too much or when new fish are put into the tank. As long as the environment is stable, the goldfish will gradually get better after a period of time.
like people, goldfish will not like to move when they are sick. At this time, goldfish do not like to swim, but also accompanied by the ulceration of fins, white spots on the body and other symptoms. Sick goldfish should be treated with medicine in time according to their condition, and the fish tank should be disinfected in serious cases.
When the water quality becomes very poor, goldfish will lie on the bottom of the water and may float, which requires the breeder to change the water in time to improve the water quality.
in order to improve water quality, people often use drugs such as water purifiers. Improper use of these drugs may make sensitive goldfish lie motionless at the bottom of the water. At this time, the change of water can be improved.
sinking to the bottom is also a means for goldfish to avoid injury. For example, when the female fish is pregnant, she will sink to the bottom to avoid the bite of the male fish.
