1. Raise several orchid longevity in a 30 cm tank If it is an adult orchid longevity, it is recommended to raise only one orchid longevity in a 30 cm fish tank, and if there is no adult orchid longevity and the body length is about 10 cm, it can raise 2-3 orchid longevity. If the body length is between 5-10 cm, 3-5 can be raised. Although the body length of Lanshou goldfish will not exceed 20 cm in adulthood, they are round in size, so the space needed is relatively large. In addition, the water body in the 30 cm fish tank is relatively small. If the number of fish tanks is large, the speed of water quality deterioration will be accelerated. Breeders should also pay attention to the feeding density when breeding.
2. Do you need oxygen to raise Lanshou goldfish in a 30 cm fish tank?If you use a 30 cm fish tank to raise Lanshou goldfish, you need oxygen. Because the water body in the 30 cm fish tank is small, the speed of water pollution will be accelerated, and the dissolved oxygen in the water will also decrease. If they are not oxygenated in time, they will suffer from lack of oxygen. Breeders can choose to take oxygen during the day and turn it off at night, which can ensure sufficient dissolved oxygen in water without affecting their rest.
3. Do you need to add salt to raise LanshouWhen raising Lanshou, you can add a small amount of salt, which can effectively kill most bacteria in the fish tank. Breeders can add some salt according to the amount of water every time they change water. But the amount of salt should not be too much, otherwise Lanshou will feel uncomfortable. In addition, attention should be paid to the types of salt. Do not use edible salt, but use special salt for fish.
