CATDOLL : CATDOLL: Signs before tropical fish give birth to baby fish, tropical fish breeding methods

There are many signs before tropical fish give birth, such as a bulging anus, a contracted anal fin, and a raised tail. As the birthing period approaches, the belly will get bigger and bigger, and the fetal spots will become more obvious. Usually, when breeding, it is placed in a breeding tank, and after the eggs are laid, the parent fish should be removed to prevent them from swallowing the eggs. The eggs will hatch in a few days, and you can feed them with water in the early stage. 1. What are the signs before tropical fish give birth, its anus will bulge, and the anal fin will always be in a contracted state, and the tail will be raised. It usually takes a month from fertilization to birth, and as the birthing period approaches, the fish's belly will get bigger and bigger, and the fetal spots will become more and more obvious. If you lower the water temperature or push the fish's abdomen, you can achieve the effect of inducing labor.

II. Breeding Methods 1. Prepare a breeding tank: To breed tropical fish, you need to prepare a breeding tank and separate it from other fish to prevent attacks. The water in the tank must be well maintained before the parent fish can be placed in it. If the parent fish have been paired, the paired fish can be placed in. If they have not been paired, they can be placed in a certain ratio of male to female.

2. Adjust the water temperature: Tropical fish have certain requirements for water temperature, which is usually kept at around 25℃. The temperature can be raised appropriately during the breeding period, but it should not exceed 30℃. In addition, pay attention to the water quality. You can put some fish tank stones in the tank to settle the waste produced by excretion, thereby preventing the water from rotting. You can also plant aquatic plants to consume energy and provide a certain amount of oxygen.

3. Mating and spawning: When the fish enter the breeding period, they will soon mate and spawn, usually in the evening, or late at night. Because there are many types of tropical fish and their habits are different, some need to be fished out in time after spawning to prevent them from swallowing the eggs, while others have the function of protecting the eggs.

4. Fry breeding: Usually, fish eggs will hatch within one day, and they do not need to be fed immediately after hatching. In the early stage, they can digest the yolk sac, and they are usually fed every other day. For fry, the size of the food must be paid attention to. Very small fish need to be fed with water, and slightly larger fish can be fed with fish worms.
