why goldfish pile up at the bottom of the fish tank? 1. Environmental changes: Goldfish will pile up together if they do not adapt to the new environment. If they are frightened when they change places, they will also cause them to pile up.
2. The water temperature is too low: If the water temperature is too low, the goldfish will pile up at the bottom of the tank. Because the temperature at the bottom of the cylinder will be a little higher than that in the middle and upper layers.
3. Disease: The goldfish piled up at the bottom of the tank may be a cold or a parasitic infection. The performance of these two diseases are different, the cold is goldfish piled up in the corner of the bottom of the tank, do not like to swim, do not like to eat, the main cause is the temperature difference is too large. Although ectoparasites also have the phenomenon of piling up at the bottom of the jar, there will also be the situation of rubbing the jar, the cause of which is bacterial infection. Breeders need to observe and judge the cause by themselves.
1, environmental changes: environmental changes or caused by shock, can not be treated, waiting for their own slow recovery. But during the recovery period, it is better not to move to a new place, nor to let them be frightened again.
2. The water temperature is too low: the water temperature needs to be raised to about 25. However, it should be noted that do not directly heat up to 25 degrees, to gradually heat up, the temperature difference is too large to easily lead to goldfish cold.
3. Disease: If you have a cold, you can raise the water temperature to 28-30 degrees, and then put a small amount of coarse salt into the water. Do not feed during treatment and keep the water clean. If it is because of ectoparasites, you can use mercurous nitrate to medicate bath, and then raise the water temperature, about 2-3 days can be cured.
