Koi is always a koi, at most in recent years there have been butterfly carp and dragon phoenix carp, and then there are more traditional koi, the main and more popular koi species or the earliest Mizoya, that is, Taisho sansei, Showa tricolor and red and white koi.
What many new aquarists don't understand is why crucian carp has popped up so many names in recent years that they haven't heard of it before.
In fact, this is just a different name of the business, although many names have long been there, we say that alloy goldfish and ground goldfish are also hybrids of crucian carp and goldfish, but some aquarists encounter crucian carp do not know what it is, what is the difference between them and grass goldfish?
I heard that there are still some cold-water parrot fish, hehe, how can it not have cold water Arowana and cold water colorful?
The ornamental fish species we can encounter so far are basically the above species, in addition to marine fish, many aquarists have not begun to raise, native fish as long as they are local life aquarists basically know, not to mention tropical fish, because most of them need to be heated and raised.
All that's left are goldfish and koi, will there be any other species?
Goldfish and koi are two completely different species, in the strict sense, goldfish is just crucian carp, and koi belongs to carp, and this is a simple difference between the two.
This problem seems to be a bit around, grass goldfish is also goldfish, goldfish is also crucian carp, through the same amount of substitution to learn, grass goldfish is also crucian carp, haha, messed up, let's slowly give them it, straighten it out.
Because the ancestor of the goldfish is the golden crucian carp, and later after the cultivation of our ancestors, they have slowly become the goldfish with a variety of varieties and bright colors, and in the strains of goldfish, we can divide them into: grass goldfish, wen species goldfish, egg goldfish and dragon goldfish, which we often say grass, literature, dragon, egg.
Other goldfish species, we do not study for the time being, we only talk about grass goldfish, in fact, they are just a little bit of crucian carp, so for some of the more beautiful grass goldfish, we can also call it golden crucian carp, to put it badly, goldfish can also be called golden crucian carp, they are not also some beautiful crucian carp? Goldfish are actually crucian carp, but we separated the four-tailed goldfish from the grass goldfish, of course, some goldfish are three-tailed, here we will not mention.
So, if we want to talk about the difference between crucian carp and koi, we actually want to distinguish the difference between crucian carp and carp.
We only need to remember two things:
One is that carp have whiskers, which is absolutely wrong, and the other is that the carp's mouth is downward, and it is slightly fat and has a short tail.
Crucian carp is not bearded at all, and the mouth is forward, the mouth shape is the same as the goldfish, most of the body is more slender, the tail will be longer than the koi, as for what dragon phoenix koi and butterfly koi are cultivated now, that is another matter, although their tails are also very long, but they must have beards and mouths downwards.
Therefore, when we understand these points, we will clearly distinguish between carp and crucian carp, the so-called grass goldfish is the crucian carp, and what gold, alloy, cold water parrot, etc., in fact, all are grass goldfish, that is, crucian carp, nothing more.
They are all a big series that should be attributed to goldfish, that is, the grass goldfish series.
We can summarize in one sentence, alloy goldfish is a crucian carp with the shape of crucian carp and the tail of a goldfish, this is the alloy goldfish, some of which are three open tails, some are four open tails, in fact, this species was first introduced by Small Japan, but it has been improved in the hands of others.
As early as 500 years ago in the Muromachi period of Japan, they introduced goldfish from China, and later in order to distinguish them from the goldfish imported from China in the Edo period, they called the goldfish at that time alloy goldfish, and then gradually improved, and the variety was more and more, but the varieties of these alloy goldfish were not too in line with the aesthetic concepts of our countrymen, so they have not been popular.
So now we see all the strange fish with crucian carp and goldfish tails, we can call them alloy goldfish, of course, even if we call them alloy crucian carp, alloy grass goldfish, it is not too much, in fact, it is so.
Ground goldfish are also improved on the breed of alloy goldfish, both in terms of body shape and tail, they must have some characteristics of alloy goldfish.
The only difference is that the tail shape of the goldfish is better than that of the alloy goldfish, their tail is somewhat similar to the taste of the current Thai lion, but it is not pleated, nor is it closed so close, it is very exaggerated to loosen and separate, and it is a bit like a goldfish with four tails, which is basically the case, this thing is not so popular in our country, but I heard that it is still very popular in small Japan, and there are many varieties, and it is also protected and supported by the government.
It's easy to tell the difference when we see the pictures.
In fact, there are still many crucian carp species on the market, of which the more famous ones, such as bristol goldfish, they are British-trained crucian carp species, as well as Shouhui Guangjin, Zhu Wenjin, etc. are small Japanese cultivation of crucian carp varieties, the reason why I call them crucian carp varieties is to facilitate everyone to distinguish them from carp faster.
In fact, we want to distinguish them, and there is a relatively simple way here, that is, you can look at their names.
All ornamental fish with gold characters and crucian characters in their names are basically crucian carp, also called goldfish, we say grass goldfish, golden crucian carp, butterfly tail goldfish, blue shou goldfish, ground gold, alloy and so on.
Any ornamental fish with a carp in the name must be a carp, for example, we say what golden koi, red and white koi, butterfly carp, dragon and phoenix carp and so on.
In this way, we are easier to distinguish, and we will not be fooled by the merchants, and finally there is a so-called cold-water parrot fish, which is actually crucian carp, but they are all red and black eyes.
So no matter how to change the name, crucian carp will always be crucian carp, and carp will always be carp.
I am a veteran of fish farming, more ornamental fish problems please pay attention, thank you!
