The fish in the fish tank are not sick.There are three reasons for their clustering, the first is that the water quality is not good, not only clustering, but also jumping tank, at this time need to change water in time.The second is not adapted to the environment of the fish tank, generally mainly new fish, quiet for a few days.The third is that the dissolved oxygen in the water is not low, and the fish will gather in the absence of oxygen, and mostly float near the surface of the water.
1. New fish resting: If it is a new fish that has just been put into the fish tank, it is very normal to gather together, because it is not adapted to the environment. In this case, don't worry. It will be all right after a few days of resting.Don't feed it during the rest period, because if you don't eat it, it will spoil the water.At the same time, do not change the water, lest the fluctuation of water quality causes it to produce stress reaction.
2. Change the water in time: If the water in the fish tank has become turbid, it indicates that the water quality is not good. If this situation gathers, it is necessary to change the water to improve the situation.Usually every other week should be changed, each time for a quarter of it, not more than a third, too much will stimulate the fish.
3. Supplement oxygen: If the oxygen in the fish tank is insufficient, the fish will also gather together. In this case, it is necessary to use oxygenation equipment to supply oxygen to the fish tank.It usually takes 2-4 hours a day to satisfy the fish's breathing, and if it is summer or rainy weather, it needs an additional 2 hours of oxygen.
