the best water for goldfish is old water, because old water not only has stable water quality, but also has bacteria that are beneficial to the growth of goldfish. Therefore, when raising goldfish, when the fish tank is equipped with a filtration system to maintain good water quality, you can change the water as little as possible, and regularly add the water reduced by evaporation. If the water needs to be changed, the tap water must be dried in advance to remove chlorine and avoid harming goldfish.
of goldfish, the water temperature must be well controlled, in addition to trying to keep the water temperature between 18-26 degrees Celsius, which is the most comfortable for goldfish, we must also keep the water temperature constant, do not appear big fluctuations, otherwise goldfish will easily get sick. When you change the water, you must not let the temperature of the new water and the old water differ too much.
goldfish is an ornamental fish that consumes a lot of oxygen, so the feeding density of goldfish must not be too high, otherwise it is easy to make goldfish anoxic. In addition, if the density is too high, goldfish will grab food and fight, and excessive excretion of goldfish is not conducive to the maintenance of water quality.
Although goldfish are omnivorous fish, many foods can be eaten by goldfish. However, when feeding, we should pay attention to feeding live food such as water fleas, which goldfish prefer, or nutrient-rich high-quality artificial feed with appropriate particle size. Only by eating well, goldfish can be healthier, not sick, and live longer.
