of tropical fish species are different, life span is not the same, some live longer, some life span is not long. Some short-lived fish, such as guppies and Mary fish, usually die after two or three years, which is a normal natural death. Fortunately, this kind of fish generally has a strong reproductive capacity, and it is easy to reproduce, so there is no need to worry about raising less and less.
of tropical fish in the case of improper management, it is easy to suffer from disease, if not treated in time, it will lead to the death of fish. Common fish diseases include white spot disease, saprolegniasis, head hole, blindfold, and so on. Generally, after getting sick, do not use medication immediately. You can first use the old three solutions of changing water, warming up, and adding salt, and then prepare medication if you can't cure it.
water quality not only leads to the death of fish due to its own reasons, but also to the sudden death of fish due to changes in the external environment. For example, the water has not been changed for a long time, and the amount of feeding is relatively large at ordinary times, which makes the water body deteriorate, the water quality is poor, and the survival of fish will be endangered if the water is not good, so the water must be changed in time at ordinary times.
fish living in the water, the change of water temperature will also have a certain impact on it, if the temperature difference is relatively large, the fish can not adapt, or the water temperature is too low to cause the fish to freeze, the fish will also die. Therefore, it is generally necessary to prepare heating rods to control the temperature above 20 C to raise tropical fish.
