Usually, after the fish has just entered the new tank, due to changes in the environment and lack of adaptation to water quality, it will sink to the bottom and remain motionless. At this time, it is necessary to suspend feeding, not to feed it, and not to change water, so as not to affect its recovery due to fluctuations in water quality. Generally, after a few days of rest, the fish will not sink to the bottom again.
If the water quality is not good, the fish will also sink to the bottom and remain motionless. At this time, what we need to do is to change the water in time. Usually once a week, if the filtration is better, it can be changed once half a month, about a quarter of the water should be changed each time, and the water temperature of new water and old water should be consistent.
Fish often have certain requirements for water temperature, especially tropical fish, if the temperature is relatively low, it will lead to little activity, and there will also be a phenomenon of sinking to the bottom. At this time, what we need to do is to raise the water temperature, generally about 20-30 degrees Celsius, so that the fish will begin to move and feed.
When a fish is sick, it will also cause it to sink to the bottom and not move. At this time, it needs to be properly warmed up, then speed up the water exchange interval, maintain water quality hygiene, and properly salt, the concentration of 0.3-0.5% is appropriate. If the treatment is not good, you need to mix the medicine into a solution and soak the fish.
