The life span of red nose scissors fish is about 4-5 years, but it can only be raised for 2-3 years. It is difficult to breed, so it is not recommended to start from small fish. It is recommended to start from about 3cm. When breeding, we should raise a few more. If they are too few, they will hide themselves. At ordinary times, the water temperature should be kept between 22-26 ℃, the pH value should be controlled between 5.4-6.8, and the water should be changed regularly. 1、 How long is the life span of red nosed scissors fish? The life span of red nosed scissors fish is generally about 4-5 years. However, due to localized recent reproduction, their life span is generally shortened and can only be raised for about 2-3 years. In addition, because its own breeding is slightly more difficult, it needs careful care. In addition to paying attention to the feeding density and maintaining environmental sanitation, it should also avoid being disturbed. 2、 Red nose scissors fish breeding precautions 1. Don't raise small fish: red nose scissors themselves are bad fish. The survival ability of small fish is lower, and the requirements for water body are higher. If they are not well raised, they are easy to die. So when you buy fish, you should choose a bigger one, and the body length must be greater than 3cm, which makes it easier to raise.
2. Raise a few more: red nose scissors are a good choice. In addition to good viewing, raising more can also make them feel more secure. If there are only 1 or 2, they often hide near water, grass or stones and dare not go for feeding, but there is no problem raising them to 8-10 tails.
3. Water temperature and quality: many tropical fish have a wide range of adaptability to water temperature, but red nose scissors have very high requirements for water temperature. They must survive in an environment of 22-26 ℃ and the pH should be controlled between 5.4-6.8. You can create scenery in the water, but don't raise too many water plants, which will compete for space and oxygen.
4. Regular water change: any fish needs a clean environment, and red nose scissors are no exception. However, if the water is changed frequently, the stimulation of new water to fish will also become a problem. The water change cycle is usually determined according to the temperature, usually about one to two weeks, one third of each time. （GongBiJianDaoYuShouMingDuoChang，YangShiShiYouShenMeZhuYiShiXiang）
