Just under the small fry must be isolated feeding. Although not all female fish eat fish eggs or small fish, some do take small fish to satisfy their hunger when they are hungry, so generally after production, they need to fish out the female fish and raise them separately, while the small fish can be raised together and wait for them to grow up slowly.
Small fish still have a relatively high requirement for temperature. If the water temperature cannot be kept, it is very easy to cause the death of the fish. Usually, depending on the type of fish, the temperature control is different. Tropical fish need to be kept above 20 degrees Celsius, cold-water fish need to keep the temperature below 20 degrees Celsius, and wide-temperature fish are not required, but higher will be better.
Feeding small fish is more troublesome, mainly because it is difficult to obtain feed, because the fish is still too small, fish food and so on can not be fed, can only feed a little migratory water. In addition, you can also choose cooked egg yolk feeding, but to control the dosage, otherwise it will easily lead to deterioration of the water body, which is harmful to the health of fish.
The first week of raising small fish do not need to change the water, let it adapt to the situation of the water body, a week after the first change of water, then can be changed every other week, each time to change a quarter of it. The temperature before and after changing water should be consistent, and the temperature difference between new water and old water should not be too large.
