The colorful giant mermaid is very popular among aquarists because of its rich and changing colors and patterns. It has the reputation of "the emperor of popular fish". In the past, it was considered to be the most difficult fish. It is one of the most popular species of reference fish. However, with the development and improvement of technology, the growth of colorful giant fish is no longer a problem. Even we aquarium enthusiasts can let it breed at home or in the aquarium. Reproduction, how does it grow?
The colorful giant is the hot fish, and the hot fish can be divided into oviparous and viviparous fish. We know that most fish are oviparous, that is, the female fish lays eggs and the male fish ejaculates, which fertilizes them into fertilized eggs. However, viviparous fish are different from the viviparous mammals. After the eggs are fertilized in the abdominal cavity of the female fish, they do not attach to the mother's body. Instead, they directly absorb nutrients from the yolk and develop into daughter fish, which are then born, so they are called Ovoviviparous.
Most fish eggs are transparent, about one millimeter in diameter. There are two types: planktonic eggs that float on the water surface and heavy-water eggs that sink to the bottom of the water. Heavy water eggs are divided into adhesive and non-adhesive ones. Within a short time after eggs are produced in the water, the egg membrane will become tough due to water absorption, and the ability to fertilize will be lost. However, almost all fish can complete the fertilization process in a short time.
There are great principles for the growth of the colorful giant mermaid
After the eggs are fertilized, they begin to develop very quickly. The cells rupture and gradually become a complete fish body. Over a period of time, the initially transparent eggs gradually form a little grayish black. When we look closely, we can find that these are the eyes of the eggs. The fish then breaks through the membrane and hatches into colorful giant mermaid larvae. The hatching time of each fish is different, and the water temperature, weather, etc. also play a big role. Under normal circumstances, if the water temperature is high, the giant fish will hatch quickly, and if the water temperature is low, the hatching will be slow. On the contrary, in extreme cases, Under high or extremely low water temperatures, it is easy to produce deformed fish. The newly born young colorful fish have weak swimming ability, and their abdomen is like wearing an umbilical sac, which makes it difficult to stretch. Within a few days after hatching, it absorbs the nutrients in the capsule, and then begins to attach to the mother's body to absorb it. Young shrimps can be fed with nutrient solution at about four o'clock in the morning. The whole process takes six to eight days before the young fish can be moved to another place to be raised.
The discus giant is a kind of weak and fearful fish, but the discus giant in the growth period is just different. The parent fish often make a strong gesture to protect the growing place, fish eggs or young fish, and occasionally Even attacking people or fishOr objects, such as straws. Therefore, during the growth process of the colorful giant mermaid, we need to transfer it to a special fish tank, and the position of the fish tank should be relatively hidden to avoid disturbing the fish from making too impulsive behaviors. This is also to prevent the nursing parent fish from occasionally eating its own larvae when surprised.
The growth process of the colorful giant mermaid requires us to observe it slowly in daily life, master its growth ability, and then understand its habits so that it can grow up healthily.
