购买蝴蝶尾金鱼的要点

蝴蝶尾金鱼是一种以龙眼金鱼为基础的物种，尾鳍像蝴蝶一样伸展。它们的尾巴伸出四片叶子，像蝴蝶一样，非常美丽。那么在购买这种金鱼的时候需要注意哪些要点呢？1.头部应宽。这种鱼观赏效果好，一般鱼生长速度更快，骨架更大；2、蝴蝶尾作为龙眼金鱼，自然以珠珠型为上品，但现在蝴蝶尾的眼球一般较小，不够突出；3.如果蝶尾的谱系良好，胸鳍末端一般是圆形的，可以作为蝶尾纯度的检验点；4.蝶尾分为直型、反翘型和扇圆型。这里的直型一般是直型，而反翘型和扇圆型则是倒弧形；图5：蝴蝶尾金鱼的尾叶末端又宽又窄。有可能这是一种从常见的龙眼金鱼中选择的尾巴形状更好的鱼，也就是蝴蝶尾金鱼的原始形状，以及不纯品种的表现。然而，扇圆尾形状的蝴蝶尾巴相对尖锐，使得左右的尾叶可以形成扇圆形状；6.蝴蝶尾金鱼的尾巴不要太大。一般情况下，最好以直线方式打开尾巴，但不应研磨尾叶，打开角度不应超过15度。我的尾金鱼有点大；7、尾长与体长之比一般大于或等于1:1，称为大蝴蝶尾，小于1:1，称小蝴蝶尾；8.蝴蝶尾巴的尾叶边缘接近一条直线。如果凹弧明显，尾巴会显得很细，观赏效果会降低，这也是鱼种不纯的表现；9.如果头部和身体的关节是平而直的，鱼的体型会更长，观赏价值也会更低。这里一般要求有一定的角度，这最像高背造型的镀金金鱼；10.尾柄和尾座一般要求鱼的尾柄短而结实，尾座应呈半圆形展开，有利于尾蝶尾形的展示。这些是我自己在鱼采摘和养鱼过程中的一些经验。这纯粹是基于我个人的审美观。如果有什么问题，我希望你能指出它，我希望它能帮助你选择蝴蝶尾金鱼

Key points for purchasing butterfly-tailed goldfish

butterfly-tailed goldfish is a kind of species based on the dragon eye goldfish with tail fins stretching like a butterfly. Their tail stretches out all four leaves, like a butterfly, which is very beautiful. So what are the key points to pay attention to when purchasing this kind of goldfish? 1. The head should be wide. This kind of fish has good viewing effect, and generally the fish grows faster and the skeleton is larger; 2. As the dragon eye goldfish, the butterfly tail naturally takes the abacus bead type as the top grade, but now the eyeball of the butterfly tail is generally small and not protruding enough; 3. If the pedigree of the butterfly tail is good, the end of the pectoral fin is generally round, which can be used as the inspection point for the purity of the butterfly tail; 4. The butterfly tail is divided into straight type, reverse warped type and fan-round type. The straight type is generally straight here, while the reverse warped type and fan-round type are inverted arc; 5. The end of the tail leaf of the butterfly tail goldfish is wide and narrow. It is possible that this is a fish with a better tail shape selected from the common dragon eye goldfish, that is, the original shape of the butterfly tail goldfish, and the performance of the impure variety. However, the butterfly tail with fan-round tail shape is relatively sharp, so that the left and right tail leaves can form fan-round shape; 6. The tail of butterfly tail goldfish should not be too large. Generally, it is best to open the tail in a straight line, but the tail leaves should not be grinded, and the opening angle should not exceed 15 degrees. My tail goldfish is somewhat large; 7. The ratio of tail length to body length is generally greater than or equal to 1:1, which is called large butterfly tail, and less than 1:1, which is called small butterfly tail; 8. The edge of the tail leaf of the butterfly tail is close to a straight line. If the concave arc is obvious, the tail will appear very thin, and the ornamental effect will be reduced, which is also a manifestation of the impure fish species; 9. If the joint of head and body is flat and straight, the fish will have a longer body size and lower viewing value. It is generally required to have a certain angle here, which is the most like the gold-plated goldfish with a high back shape; 10. The tail handle and tail seat generally require that the tail handle of the fish be short and strong, and the tail seat should be unfolded in a semicircle, which is conducive to the display of the tail butterfly tail shape. These are some of my own experiences in the process of fish picking and fish raising. It is purely based on my personal aesthetic view. If there is something wrong, I hope you can point it out, and I hope it will help you in selecting butterfly-tailed goldfish
