Before the main text of the article begins, let me mention this interesting topic to you: that is, when the older generation raised ornamental fish in the past, in fact, it was rare to say that ornamental fish were sick, and then it was not easy to treat or ornamental fish was more difficult to raise. But now when we raise ornamental fish, most of them will find ornamental fish particularly difficult to raise, and it is easy to get sick and die. Do you know why?
In fact, in the era when our older generation raised ornamental fish, there were very few varieties of ornamental fish to choose from. In the north, goldfish and koi are basically the mainstay, while in the south there will be relatively more, and later some small tropical fish will begin to appear on the stage of the aquarium circle.
goldfish
What must be emphasized and popularized here is that the goldfish koi is different from most of the tropical fish we raise now. Where is this difference? Let's take an example.
We all know that there is an animal in the animal world called a cold-blooded animal, which generally refers to some reptiles such as snakes, lizards, turtles and so on. The reason why they are called cold-blooded animals is because their body temperature cannot be regulated by themselves, but they need to use the external environment to help regulate body temperature. In other words, the body temperature of cold-blooded animals changes with the temperature of the external environment, and cold-blooded animals have another academic name " warming animals" in academics.

We all know that most snakes need to hibernate, because the temperature in winter is relatively low, so the body temperature of snakes is relatively low, and they cannot give them enough energy to move. Therefore, they need to sleep to ensure that their energy is not excessively consumed, and they save their physical strength in turn. It's a bit like sleeping with us humans and not feeling hungry. Similarly, if you like to raise turtles or lizard friends should know that raising these animals in the temperature is relatively low when the need to add thermal light, and it is best to have a fixed time every day to bask in the sun, which is more conducive to their growth.
So back to our topic, in fact, most of the tropical fish we raise now are equivalent to these cold-blooded animals, or we call them "cold-blooded fish". Because tropical fish are difficult to regulate their body temperature by themselves. Or it is almost impossible to regulate body temperature by itself. So like cold-blooded animals such as snakes, lizards, and turtles, they need to meet their body's energy needs through the heat transfer of external temperature.
Wait, maybe this is not direct enough, in fact, the more authoritative statement should be: except for mammals and birds, other animals are cold-blooded animals, and fish are no exception.
Koi fish
Let's look at goldfish and koi fish, they are more powerful. When the temperature of the external environment changes, they respond in this way: when the ambient temperature drops, their membrane phospholipid saturation will increase, so that the temperature of their own body will increase, in this way to maintain their body temperature is not too low, but this usually needs to consume more energy, so the oxygen consumption of goldfish is relatively large.
Friends who have raised tropical fish know that in fact, the oxygen consumption of tropical fish is not so high, so their ability to maintain their body temperature in this way is relatively poor. Therefore, when the temperature of the surrounding environment is relatively low, generally below 10 degrees, they are likely to freeze to death due to the inability to maintain their body temperature well, or cause a very low physique, become very weak, and are prone to bacterial fungus infection.
This goes back to the question we asked at the beginning, because the older generation raises more goldfish koi fish, so these are not easy to get sick due to changes in temperature, and naturally it is easier to raise. Most of the very beautiful ornamental fish we raise now are actually tropical fish. So sometimes our water temperature control is not good, if the fluctuation is a little more violent, we may feel nothing, it will fluctuate 2-3 degrees, but in fact, for tropical fish, this temperature is very variable.

So here we extend that when raising tropical fish, the main thing is that the water temperature should be kept constant. Even if the water quality is slightly worse, they can tolerate it and will not immediately put their lives at risk. But as long as the temperature changes too drastically, they can easily appear in a variety of situations.
This is the difference between the older generation of ornamental fish and our modern ornamental fish, which is essentially because the varieties of ornamental fish are different, so the physical skills of the fish are also different, which leads to the difference in the difficulty of raising fish.
So back to what we have always emphasized at the beginning of fish farming, that is, to understand this ornamental fish, what kind of background information it is, what kind of water quality they like, what kind of water temperature they are more adapted to, and the more specific the understanding, the more conducive it is to our party This ornamental fish is well raised.
Here is the fish farming said, like to raise ornamental fish friends, may wish to move to point out a concern, all the fish farming water to know is here!
