Why does the parrot fish lie under the water? What if it doesn't move under the water

Nautilus always lies still at the bottom of the aquarium, maybe there is something wrong with its swim bladder, maybe it is an imbalance. In this case, it can't swim normally. When swimming, it will turn over and float on the water, so they can only lie underwater all the time. It is also possible that they are ill, such as "water mildew". At this time, they need to be isolated and disinfected in time. 1、 Why does Nautilus lie underwater? Nautilus is a kind of fish in the middle of the fish tank. Under normal circumstances, it moves in the middle of the water. If they have been lying underwater, they may be ill. First of all, there may be something wrong with their swim bladders, resulting in their imbalance, so they can't swim normally. Once they swim, they may turn over and float on the water. Therefore, they generally do not continue to swim, but lie underwater. In addition, it may also be caused by other diseases, such as "water mildew". This disease can be judged by observing the body of parrot fish. If you get this disease, the body of parrot fish will rot. 2、 What to do if the parrot fish lies still underwater? If the parrot fish lies still underwater, measures should be taken in time according to the specific reasons. If there is only a problem with the swim bladder leading to the imbalance, you need to change one-third of the water immediately and about one-fifth of the water in the next few days. After the first water change, add about two bottle caps of nitrifying bacteria, and then add one bottle cap every day for a week, which can be basically cured. If it is "water mildew", considering that the disease is contagious, it needs to be isolated for treatment. The sick fish are fished out and placed in a separate fish tank, and then treated with yellow powder or potassium permanganate solution. It is better to change water and disinfect the original fish tank in order to ensure that other parrot fish are not infected. （YingWuYuWeiShenMeTangZaiShuiXia，TangZaiShuiXiaBuDongZenMeBan）
