? The oxygen consumption of goldfish is relatively high. Normally, only four to eight goldfish can be kept in a tank of 1.5 meters, so as not to cause them to lack oxygen. Other fish with low oxygen consumption can be kept about 15 in such a large tank.
if they don't get oxygen for one night? Whether goldfish will die if they don't get oxygen for one night is related to their feeding density and the space of the fish tank. It can be divided into two situations:
1. If the fish tank itself is relatively small and the number of goldfish raised is relatively large, if oxygen is stopped, Their consumption can easily lead to insufficient oxygen content in the water, which can lead to their death.
2. If the space of the fish tank is relatively large and the number of goldfish is relatively small, it will not cause them to die if they do not use oxygen overnight.
So in order to prevent them from lacking oxygen, try not to feed them at night, which will increase their consumption of oxygen. If the feeding density is high, it is better to supply them with oxygen continuously at night, or use light to illuminate the aquatic plants when night comes, so that the aquatic plants can produce some oxygen. In this way, the goldfish will not die in the case of sudden oxygen loss at night.
