70 centimeters of water depth can raise fish, but need to see what kind of breed is raised. If it is a small goldfish, it is generally recommended that the water depth be 40 centimeters. The water depth should not exceed three quarters of the fish tank as far as possible, because the oxygen content of too deep water will be relatively low, which is not suitable for fish to survive. In the case of good oxygen supply equipment, goldfish can also be raised at a depth of 70 centimeters. If you find that the goldfish keeps spitting bubbles frequently on the surface of the water, it means that the goldfish may lack oxygen. At this time, it is urgent to change the water. At the same time, only one third of the original water needs to be replaced. If it is tap water, it needs to be sterilized in the sun to avoid the discomfort of goldfish caused by excessive chlorine in the water. However, it should be noted that fish in deep water should not be suddenly raised in shallow water, otherwise it is easy to cause turning over.
water for raising goldfish? The water for raising goldfish is related to the species, temperature and quantity of fish. Taking Lanshou as an example, in the hot summer in the south, Lanshou can not only survive in 50 centimeters of water, but also breed in one meter of water. Therefore, some people will keep them in small fish ponds outdoors. Grass goldfish, for example, are generally suitable for breeding in water 60 centimeters deep. Longevity and Guoshou are suitable for living in water 40 centimeters deep.
