Only parrot fish with red devil gene will start. And different species of parrot fish have different starting degrees. The head of a fish with excellent genes can grow very big. Fish with poor genes are very difficult at first. The parrot fish after starting can be divided into hard head and water head. Head parrot fish's head will shrink after being stimulated by the outside world. Therefore, during the beginning of parrot fish, try to avoid being frightened. 1、 Will parrot fish start? Some parrot fish can start. The important factor that determines their start is genetics. Parrot fish that can start often have excellent red devil genes. Different species of parrot fish have different head sizes. Like King Kong Parrot Fish and Dharma parrot fish, their starting effect is very obvious, and their heads can grow very large. The initial effect of the God of wealth parrot fish is weaker. Compared with King Kong and Dharma parrot fish, its head will be much smaller. The common parrot fish without red devil gene in its body is more difficult to start. Parrot fish that can start can also be divided into hard head and water head. Generally speaking, hard headed Parrot Fish do not shrink their heads. When the Nautilus is stimulated by the environment, its growing head will shrink. 2、 How to raise parrot fish? 1 Water temperature: control the temperature between 28 ℃ and 29 ℃. Providing it with a suitable temperature environment is conducive to its start.
2. Water quality: it prefers clean and weakly acidic new water. It is best to change the water every day to ensure the freshness of the water body. When changing water, only one fifth of the old water needs to be replaced.
3. Oxygen supply: its respiratory system is not very developed, so it is necessary to increase the dissolved oxygen in the water so that it can breathe normally. An oxygen pump can be installed in the fish tank to pump oxygen into the water for 1 ~ 2 hours every day.
4. Feeding: its feeding habits are complex. When feeding, red insects, rich shrimp and small fish are the staple food, which can be fed with special feed for Nautilus. Feed them 1 ~ 2 times a day to ensure the nutritional supply they need to start. （YingWuYuHuiQiTouMa，ZenMeYangNengQiTou）
