different fish out after the situation is often not the same. If they are oviparous, they will swim freely after hatching, and if they sink to the bottom, they will be dead. But if it is oviviparous fish, just come out often will sink to the bottom, they can also absorb the yolk sac, absorption will be active. At this time can be carefully observed to see if it will move, will move that is alive, will not move is dead.
1. Feeding: The small fish does not need to be fed on the first day after birth, because it has not absorbed the yolk sac at this time, so it will not ingest, and it will not eat after feeding. Wait until the next day, yolk sac absorption, it is necessary to provide food, usually choose cooked egg yolk, gently twist a little into the water can, too much will bad water, conditional, it is best to feed migratory water, this food is more nutritious.
2. Water change: The small fish does not need to change water in the first week after birth. At this time, it is still relatively weak and cannot adapt to the fluctuation of water quality, so it must not change water. After a week, the fish has grown up a little, the water quality is aging, it needs to change the water. Don't change too much water for the first time, usually one fifth of it is OK.
3. Heat preservation: When raising small fish, you must pay attention to heat preservation, and the temperature must be constant, so that the fish will not have problems, otherwise there will be a stress reaction, and even lead to the direct death of the fish.
