Butterfly-tailed goldfishfish is the most beautiful. Butterfly-tailed goldfish is one of the dragon species of goldfish. In the past, due to the lack of understanding of Japanese goldfish, many people misunderstood that they also have inverted tail fins. The Japanese Tosa Goldfish is the butterfly tail of China. In fact, Tosa Gold has three tails, which is not taken by China. Moreover, Tosa Gold is developed from Ryujin, belonging to the cultural goldfish. It has normal eyes and is obviously different from the butterfly tail of the dragon species. How to select butterfly tail?

Butterfly

Tosakin is a very famous goldfish species whose tail is mainly used for ornamental purposes. Although the tail is not as lively and lively as the Chinese butterfly tail, its instant freeze-frame photos are enough to fascinate people. down the crowd. I have been paying attention to related Tosakin websites in Japan for some years. From the initial appreciation of photos to the current research texts, although I don’t understand Japanese, I still use the help of translation software and related pictures to understand a Probably, after a period of pondering, there is still some harvest.

The Japanese are very meticulous in raising soil and gold. From the needle seedlings on the 7th to the 10th, a series of screening began, and the screening process also showed its profound accumulation and scientific analysis. I Thinking about this, it is beyond the reach of many domestic industry players. Combining my experience of raising butterfly tail over the years and the reference of some materials in the process of Tosakin breeding, I would like to talk about the selection and breeding of butterfly tail at a shallow level. There are some personal partial views, after all, I am a family Breeding is not a fishing ground, so I still hope that the majority of fans will correct and exchange the incorrect place.

Butterfly fry are generally around 10 days old, the tail has begun to differentiate, and the obvious four-tailed shape can already be seen. If you want to start picking at this time, you can first eliminate the single-tailed or deformed, and then keep it. In the four-tailed fry, you can also choose further, that is, look at the parent bone. The angle between the parent bone on both sides should be selected between 120° and 90°. Why do you choose this? It can be found that if the tail is flattened to 180°, it will be very rigid, and the ability of such fish to maintain balance will be poor. When you raise it hard, it will fall over in winter, which is a pity, so it is still eliminated in advance. Avoid wasting effort.

In the subsequent growth process, you can gradually eliminate the three tails (mainly refers to the top and bottom splits), and control the density of the fry, because the control is not good at this time, you will find that there will be a lot of fish The tail has grown, but the other fins on the body are also growing, and it has a smell similar to the skirt tail. Personally, I think the proportion of other fins in a good butterfly tail should be normal. At this stage, if you observe carefully, you can also filter out bad performances such as creases in the tail, crooked tail cores, and sloping tail cores. At this stage, if there are sakura-tailed fish with inconspicuous splits or fish with soft tails, it is recommended to keep them all. For some fish with small splits, they will split after 1 month of age, and their tails are soft. In the subsequent swimming process, the parent bones will gradually exercise, and this fish is more likely to turn up the tail.

At about 2 months of age, you can clearly observe the tail of the fish from top to bottom. I personally think that the tail is still very important for the performance of the butterfly tail. I have also written an article about the tail. Interested friends can go to search. The tailstock is like the skeleton of a folding fan. The bigger the tailstock, the stronger the support, and the better the tail display will naturally be. At this stage, you can also start to pay attention to the width of the end of the lower tail and the shape of the arc of the edge of the tail. Excellent fry can be selected at this stage.

During the fry period, it is recommended not to feed the fry too much. From my experience, because I mainly feed broken adult fish food, it is extruded feed. It is very swollen, and the whole fish is in a triangle shape. I personally think that such a body shape is not good. Moreover, maintaining a certain hunger for the fish and maintaining the foraging state is conducive to swimming more and exercising the hardness of the parent bones.

When the fry is 5cm, you can turn the fry over and select the fry, that is, look at the bottom of the tailstock. If the tailstock is in the shape of ?? or ??, such a fish is very good. It may be an upturned tail shape. In addition, it is recommended to keep fish with an even and full ? shape. The performance of such a fish's tail will not disappoint you in the future. .

In the process of raising butterfly tail, it is recommended to try the Japanese way of raising Tosakin, which is to use a round pot-shaped container. In this shape of the container, the fish will have more time to swim. There are many, this is a good way to exercise the pro-bones. After the tail is set, it can be put into the rectangular water tank for feeding.

Finally, let’s talk about the cultivation of ying scales (landscape colors) in the butterfly tail. I have also communicated with the industry in Rugao about this issue. Its materials include blue and white broodstock and five-flowered broodstock. And red and white broodstock, of course, this will take several generations, and interested friends may wish to do a test by themselves.
