Newborn fish are usually fed the next day. Most of the fish are oviparous, a few are ovoviviparous, no matter what kind, after birth will take the yolk sac, this is its nutritional supply, before the absorption, it does not need to eat, so do not have to feed. Usually a day later, the yolk will be absorbed, this time to feed a little water or cooked egg yolk.
1. Migratory water: It is the best for the small fish to eat migratory water. It contains a lot of paramecia. It is a very good food. It can supplement protein and accelerate the growth of the small fish. However, the return water is not easy to get, you need to get it in the wild lakes or ponds, and you must ensure that there is no pollution.
2. Cooked egg yolk: Cooked egg yolk is also common for small fish to feed, but its amount is not easy to control, so you can't feed the whole yolk. Wrap the yolk with gauze, and then gently twist it a little. It's OK if it's about the same size as a bean grain. It is better to use a special vat to feed, so as to avoid the deterioration of the water body caused by egg yolk.
3. Soybean milk: Compared with cooked egg yolk, soybean milk is not easy to spoil water, but it is seldom used in general domestication. It is used in large farms. Like milk, it is rich in protein and is a good feed.
