The life span of the red-nosed scissors fish is generally about 4-5 years, but due to localized recent breeding, their life span is generally shortened, and they can only be raised for about 2-3 years. In addition, because of its own slightly more difficult breeding, so need careful care, in addition to pay attention to the breeding density, maintain environmental hygiene, but also to avoid it being disturbed.
1, do not raise small fish: red nose knife fish itself is not easy to raise the fish, the survival ability of small fish is lower, the water requirements are higher, it is easy to die if not well raised. So when you buy fish, you should pick a bigger one, and the body length must be greater than 3 centimeters, so that it is easier to raise them.
2, raise a few more: Red nose scissors group is a very good choice, in addition to a good ornamental, raise more can also make them more sense of security. If there are only one or two, they will often hide near water plants or stones, and they dare not go to feed, but it is no problem to raise 8-10.
3. Water temperature and water quality: Many tropical fish have a wide range of adaptation to water temperature, but the red-nosed scissors are different. They have extremely high requirements for water temperature. They must survive in an environment of 22-26 ℃, and the pH should be controlled between 5.4 and 6.8. Water can be landscaped, but do not raise too many aquatic plants, which will compete for space and oxygen.
4. Change the water regularly: Any fish needs a clean environment, and the red-nosed scissors are no exception. However, if the water is changed frequently, the stimulation of the new water to the fish will also become a problem. Usually, the water exchange cycle is determined according to the temperature, usually about one to two weeks, one third of each time.
