how to Breeding goldfish

You have seen that in the aquarium, female goldfish have eggs in their stomachs all year round, but the age of female fish should be at least 6 months. In my opinion, if the age of the goldfish is 1 year or more, then the amount of hatching is much higher the young of the fish are much healthier and the growth of the baby is much better.

When laying fish eggs, keep in mind one more aspect which is the fish species All species of goldfish can breed with each other, but never lay eggs of goldfish in this way, because if one species of goldfish is bred with another species of goldfish, the baby fish will not be good. The color or tail of the fish is all bad. Maybe. When laying eggs, lay in one species of goldfish.

Aquarium preparation for breeding

A pair of 4-5 inch goldfish can be easily bred in aquariums 15 inches wide, 15 inches high, and 24 inches long. It is better not to give filters in the aquarium in which the breeding will be done. The filter lifts the water from the bottom.

In this case, if the egg is hatched, the finger goes under the stone by pulling water. Aerators can be arranged to fill the oxygen deficiency of water. Both male and female fish eat fertilized eggs. For that, both male and female fish have to be kept separate from their eggs.

Goldfish need to lay eggs

You can lay goldfish eggs in an aquarium that holds at least 50 to 60 liters of water to lay eggs, but you cannot keep 4 fish 4 to 5 inches larger at a time in this size aquarium. If you have to lay more than one fish egg at a time, it will take up a large space in that proportion.

After placing the breeding box in an aquarium, healthy, normal male and female fish should be left in that breeding box at night. As a result, the fish eggs will come out through the net of the breeding box and wear down. As a result, the fish will not be able to destroy the eggs.

When the water is old, leave the fish in the water in the evening. Do not give any food. This fish usually lays its eggs from very early in the morning till a little early in the morning. You can easily understand the laying of eggs of this fish, if you notice a little, you will see the girl chasing the fish behind the fish and laying eggs on the tree or the rope. If it’s too late for you to wake up, pick up the tree shoots or ropes in the aquarium and see if the eggs have soapy grains on them.

If so, remove the large goldfish from the seventy aquariums, and the longer you wait to pick up the fish, the more the fish will eat their eggs. Pick up the big fish dip a little bit of methylene blue in the aquarium, and keep bubbling in the water with the help of the aquarium pump, if you have been bubbling before, then you don’t have to run again.

Remember not to run any filter in the aquarium, if you run the filter, the fish eggs will get stuck inside the filter and get wasted. Goldfish eggs usually hatch within 24 to 48 hours, depending on the temperature of the water. Do not use a water heater for hatching eggs. When the eggs hatch, you will see the baby sitting on the wall or the tree, after 1 or 2 days you will see if the baby is swimming in the water.

If you see the baby swimming, you know it’s time to feed the baby. These babies should be given very fine Daphnia at first. After 10/12 days, when the baby is a little older, give Daphnia a little bigger. If you see that the number of babies in the aquarium is too much, then after 5/6 days the babies will have to be put in a bigger place, otherwise, the baby will die under pressure.
