First, a good goldfish variety.
Grass goldfish is somewhat similar to crucian carp, and it is also one of the best varieties of goldfish. Because of its strong body shape and relatively strong adaptability, it can generally survive in water at 0~39℃. Moreover, the golden goldfish's body is red and white, which looks a bit like koi fish. It doesn't feel much about the change of temperature, and its vitality is very tenacious. In addition, because of its rich head, lion-headed goldfish is very ornamental, relatively resistant to low temperature at ordinary times, and its price is lower than other goldfish, which is very suitable for novice breeding.
Second, the matters needing attention when raising goldfish
Goldfish are not particularly demanding of their own growth environment, but it does not mean that they do not adjust their living environment. If the water quality changes or the water temperature changes suddenly, they are prone to discomfort, so it is necessary to ensure a stable environment. And you must not directly use tap water to breed goldfish. Tap water contains a lot of chlorine, which will do harm to the health of goldfish. It's best to put tap water in the sun for a few days before using it. Goldfish will not feel full, so the feeding amount must be controlled during feeding, otherwise the goldfish will be suffocated.
Compared with other pets, the goldfish breeding method is still very simple, but it also needs a certain sense of responsibility. You can't buy it and put it in a fish tank, otherwise it will easily starve to death. Since you choose to keep goldfish, you should provide them with a suitable growth environment as the owner while they bring ornamental value to everyone.
