What is the cause of the fish lying on the bottom of the cylinder?

Fish are ornamental not only because of their gorgeous appearance, but also because of their dynamic beauty, but sometimes they lie motionless at the bottom of the tank, in addition to normal sleep, there are likely to be health problems. Let's take a look at the cause of the fish lying at the bottom of the tank.

1. Indigestion

Slowly the fish will go through the adaptation period and finally have an appetite after being hungry for a long time. At this time, we often make such a mistake: when we see the fish finally begin to eat, we want to feed more, so we feed more with a shake of the hand. If the fish eat too much, it is easy to get indigestion and hide under the water to eat slowly.

2. Water temperature

Too low water temperature will affect the appetite of fish, especially the mixed culture tank, the best water temperature of different fish is different, it will cause some fish to eat very full while some basically do not eat, and will not have the strength to swim around, and too low water temperature can easily cause water mildew.

3. Poisoning

If it is summer, if the light is sufficient and the temperature is not well controlled, the overnutrition of the water body is easy to breed algae, and the excessive algae is likely to secrete some toxic substances that paralyze the senses and nerves of the fish, and the fish naturally lie down together.

4. Disease

If the fish lies at the bottom of the water and has symptoms such as weight loss and ulceration on the body surface, then unfortunately, it is likely to have inflammation of the swim bladder, and this condition should be isolated in time, while disinfecting the original tank to avoid infecting other fish. for sick fish, drugs should be used according to different conditions.
