The beautiful tail has always been the pride of goldfish. Whether it is a first-time goldfish breeder or a long-time aquarist, the goldfish tail can attract everyone's attention, and they are very concerned about the appreciation of the tail. Since ancient times, the breeders of goldfish have never neglected the improvement of the tail of goldfish, and they have always tried their best to obtain the tail shape that they are satisfied with.

Goldfish

At present, the evaluation of the tail in various website forums is also There are many, some are easy to understand, good comments such as broad tail and elegant long tail, almost such as curling, asymmetry and so on, I will not explain too much. However, some evaluations will be more professional. Good evaluations such as four big tails, full tail leaves, full tension, etc., poor evaluations such as clip tail, three tails, Yao, etc. , Experienced and old aquarists naturally understand it, but many early-stage enthusiasts are often confused and guessed repeatedly, but to no avail. What I mainly want to discuss with you is this content:

Let’s take a look at some professional terms about goldfish tails:

“Tail leaf”: both long tail and short tail It is the same, first there are 2 left and right lobes, each lobe is divided into upper and lower caudal lobes, a total of 4 caudal lobes.

This makes it easy to understand four open tails. This is mainly for long-tailed fish. The left and right 2 petals must be separated, not necessarily all of them. Usually, the tail length can be separated. If more than 2/3 of the product is separated, it is considered a genuine product, otherwise it is a defective product, which lacks that elegant attitude. It is easy to understand that the tail leaves are full, which means that the tail leaves are wide and round.

Short-tailed fish are usually described by words like four-tailed and three-tailed. Four-tailed means that the left and right 2 petals are separated, which is usually a sign of excellent genetics and the best choice for buying fish. Due to the characteristics of the short tail, the requirement for separation is not as high as that of the long tail, and half of it meets the standard, and it can be shorter. Three tails means that the left and right 2 petals are not separated and connected together, which should be regarded as a defective product. However, there are many different opinions on the standard of three tails for Lanshou in the short-tailed variety. My point of view is that the three tails should not be classified as inferior products. They still have good ornamental value, but they cannot be used for reproduction, because the three tails are the performance of goldfish degeneration and anti-ancestry.

Tension: This word is used a lot, and it is indeed very vivid. Tension means a vigorous opening. There are many scopes of this word, and the following focuses on the explanation:

First of all, let’s talk about the side view of the long-tailed fish. The more beautiful, and the fish's swimming posture and balance are also excellent. On the contrary, it is called pinching tail, and the fish appears to be lifeless and uninspired.

From the top view of the long-tailed fish, the left and right 2 caudal lobes are widely separated from left to right at the base of the tail, which is due to the structure called golden seat in the middle of the two caudal lobes. The golden seat is borrowed from the Japanese name for the part of the goldfish in Ranju, but it is still appropriate here. The fish with full force looks very dynamic when looking down, and the tail is very beautiful. On the contrary, the lack of left and right tension at the base of the tail is called clamped tail, which is not beautiful; but the tail of this tension foot should gradually become softer, and gradually have a tendency to close backwards, otherwise it will appear very stiff, which is not conducive to the fish. Balanced, the fish swims very tired and is not a good fish.

The tension of the short-tailed fish is basically similar to that of the long-tailed fish in appreciation.

The tension of the Lanshou tail needs to be mentioned separately, because everyone recognizes the Japanese Lanshou. The tail is better than that of China Life. Rishou has a unique understanding of the tension of the tail. The tail of Lanshou also adopts the standard of Rishou, which is indeed different from domestic short-tailed fish such as tiger head. The most important thing about Rishou is the bird's-eye view. The tensile Rishou tail refers to the type of tail with a straight shoulder on the left and right lobes, or a tail that leans forward slightly. The golden seat plays the key left and right here, supporting The fins on the left and right tail and shoulders are opened. Such a tail looks powerful when viewed from above, and it is said that Lan Shou's graceful swimming posture also benefits from this beautiful tail. And China Life is really not good in this regard. From a top view, the angle between the two tails and shoulders is very small, and there is no tension at all. This is called Yao. Although it swims very fast, it does not have the kind of Japanese life tail. sense of strength. This is the area that everyone thinks China Life needs to improve the most. From the side view, China's longevity tail is better. It absorbs the upturned naughty appearance of some Japanese longevity tails, which is also a manifestation of the tension of the upper and lower tail leaves.

Let's talk about butterfly tails. Everyone has a consensus on the tail shape of butterfly tails. They all like the tail shape of the tail and shoulder fins, which are really beautiful. What I want to mention here is that in addition to the shape of the two tail leaves in front of the butterfly tail, aquarists should also pay attention to the two tail leaves at the back. These two tail leaves should be as long as possible, and the tail leaves should also be wide and full. This is not only about appearance It is more beautiful, and it plays a very important role in the balance of the butterfly tail type goldfish. Everyone knows that the butterfly tail with its tail sloping forward looks beautiful, but it is easy to plant. The two wide and full tail leaves at the back are just fine. serve as a valuable balance.
