亚洲龙鱼的外观特征

亚洲龙鱼

亚洲龙鱼是价格昂贵的龙鱼中最受欢迎的物种。事实上，亚洲龙鱼最早在东南亚发现。亚洲龙鱼根据其来源和颜色可分为以下几种：

1。蓝龙鱼（细节）：蓝龙的每个鳍都是青色的，鳞片是青色的。吻端呈黄色，成鱼时全身呈金蓝色，故名青龙。黄尾金鱼和青龙很相似，只是后面的三个鳍是黄色的，价格比青龙略高

2、红尾金鱼：它和小时候的过背金鱼（详细介绍）一样。它是蓝色的，底部是绿色的，浅红色的，圆点内有一个金色的薄边框。淡红色的鳞片在形成时和之后会变成金黄色，唯一的区别是背鳍和尾鳍上部是黑色的，尾鳍下部和臀鳍是红色的，金色的鳞片条会到达鳞片的顶行，从腹部鳞片开始。这一特征可分为十字背金和红尾金龙的区别元素。顾名思义，好的红尾金龙泉关注的是尾鳍和臀鳍是否呈暗红色，而且越红越好。并非每一条俗称红尾金鱼的龙鱼都有红尾鳍的特征，其中一些只有轻微的红色甚至无色，腹鳍和胸鳍呈粉红色，带金黄色。

第三级是常见的红尾金龙：后三鳍呈浅橙色，黑色骨架和条纹明显。

3、交叉背金龙：幼鱼呈蓝色时，其特征是绿色底部呈浅红色，圆点内有一个金色的薄框架。当它生长时，光曲音阶框架将变成金黄色，金蓝色或绿色的底部音阶条将到达音阶的第五行，横跨整个深绿色的背部。除了鳞片，红发和怒金的区别是怒部和臀鳍的区别，背部和尾鳍的上部应该呈现深蓝色

4、红龙：可以分为四类。它们分别是血红、辣椒红、橙红和金红色。辣椒红龙有鲜红色的鳃盖和鳞片框架，主要带有明亮的红外边缘。每个鱼鳍也是红色的，吻也是红色的。如果光线关闭（因为鱼缸的光线具有红色波长，所以当光线打开时，鱼身的颜色并不完全正确），鱼鳞是蓝紫色的，幼鱼的嘴唇是弯曲的，头部是尖的，成鱼的鱼鳍是红色的。血红龙的体色没有辣椒红龙的鲜红色鳞片框架，鳃盖上也没有明显的深红色鳃痕，但均匀分布在全身，但颜色仍以红色为主，1号龙基本无色。幼龙鱼的嘴是平的，头部不锋利。成鱼的鳃盖呈浅橙色，鳍不明显呈红色或浅橙色，鱼鳍和尾鳍呈浅橙色。高背红尾金龙和红尾金龙的杂交种。高背红尾金的出现使得背背过背的金龙变成了。目前，有更多有争议的鱼种。两者之间的区别仅在第六排！而高质量的高背红尾金则有可能出现过背！（概率不高）因为它也继承了金龙的血脉。一条真正的背背金龙。生长后缩放颜色。通过高背红尾金并不幸运。可以进行比较。区别在于血液。所以纯十字背金龙的价格仍然很高并不是没有原因的

5、七色龙、桐岩、血红金龙：这一系列龙鱼品种是由赤龙十字背金龙改良而来的。每个家族的名字都不一样。但不是以这种方式繁殖的幼虫会长大。它们和海报一样华丽。一切都取决于个人表现。特殊的龙包括背部异常的“骆驼龙”、眼睛异常的“盲龙”、连体身体异常的“双头龙”、背部鳞片异常的“独龙”、体色异常的白化“雪龙”、蓝色身体的“黑神龙”、真红眼白化物种的“红眼龙”、透明鳃盖的“熊猫龙”、，头部有更多眼睛的“二郎神”，以及其他长相特殊的龙鱼。这些龙鱼并不常见。在人们的特别收藏下，由于它们的稀有性和独特性，它们的价格上涨了

Appearance characteristics of Asian arowana

Asian arowana

Asian arowana is the most popular species of arowana with high price. In fact, Asian arowana was first found in Southeast Asia. Asian arowana can be divided into the following types according to its origin and color:

1. Blue arowana (details): each fin of the blue dragon is cyan, and the scales are cyan. The snout end is yellow, and the whole body is golden and blue when adult fish, so it is called Qinglong. The yellow-tailed goldfish is very similar to the green dragon, except that the rear three fins are yellow, and the price is slightly higher than the green dragon

2、 Red-tailed goldfish: It is the same as that of the over-back goldfish (detailed introduction) when it is young. It is blue with a green bottom and light red with a gold thin frame inside the dot. The light red scales will turn into golden yellow when it is formed and after it. The only difference is that the dorsal fin and the upper part of the tail fin are black, the lower part of the tail fin and the hip fin are red, and the golden scale bar will reach the top row of the scale, starting from the abdominal scale. This feature can be divided into the distinguishing elements of the cross back gold and the red tail gold dragon. As the name suggests, a good red tail golden dragon spring focuses on whether the tail fin and hip fin are dark red, and the redder the better. Not every arowana commonly known as red-tailed goldfish has the characteristics of red-tailed fins, some of which are only slightly red or even colorless

The first level is the super red-tailed golden dragon: the seven fins are all red in color, especially the last three fins, with golden scales

The second level is the Class A red-tailed golden dragon: the rear three fins are red, and the ventral and pectoral fins are pink with golden yellow

The third level is the common red-tailed golden dragon: the rear three fins are light orange, and the black skeleton and stripes are obvious

3、 Cross-back golden dragon: When the young fish is blue, it is characterized by light red on the green bottom with a golden thin frame inside the dot. When it grows, the light warp scale frame will turn into golden yellow, and the golden blue or green bottom scale bar will reach the fifth row of the scale, across the entire dark green back. In addition to the scale, the difference between the red hair and the angry gold is the difference between the angry part and the hip fin, and the upper part of the back and tail fin should show dark blue

4、 Red Dragon: It can be divided into four categories. They are blood red, chili red, orange red and golden red respectively The chili red dragon has bright red gill cover and scale frame, mainly with bright infrared edge. Each fin is also red, and the snout is also red. If the light is turned off (because the light of the fish tank has a red wavelength, so the color of the fish body is not completely true when the light is turned on), the scale is blue-violet, the lips of the young fish are warped, the head is pointed, and the fins of the adult fish are red. The body color of the blood red dragon does not have the bright red scale frame of the chilli red dragon, and there is no obvious deep red gill mark on the gill cover, but it is evenly distributed throughout the body, but the color is still mainly red. The No. 1 dragon is basically colorless. The mouth of the young dragon fish is flat and the head is not sharp. The gill cover of the adult fish is light orange, and the fins are not obviously red or light orange, and the fins and tail fins are light orange. A subspecies that is a hybrid of the high-back red-tailed golden dragon and the red-tailed golden dragon. The appearance of the high-backed red-tailed gold has made the over-backed gold dragon become. At present, there are more controversial fish species. The difference between the two is only in the sixth row! And high-quality high-back red-tailed gold has the possibility of over-back! (The probability is not high) Because it has also inherited the blood of Golden Dragon. A real over-backed golden dragon. Scale color after growing. It is not lucky to pass the high back red tail gold. Can be compared. The difference is blood. So it is not for no reason that the price of the pure cross-back gold dragon is still high

5、 Seven-colored dragon, Tongyan, and blood-red golden dragon: This series of dragon fish varieties are improved by the red dragon crossing the back golden dragon. The names of each family are different. But the larvae that are not bred in this way grow up. They are as gorgeous as the posters. Everything depends on individual performance. Special dragons include the "camel dragon" with abnormal back, the "blind dragon" with abnormal eyes, the "double-headed dragon" with abnormal conjoined body, the "one dragon" with abnormal back scales, and the albino "snow dragon" with abnormal body color, the blue body "black god dragon", the "red-eyed dragon" with true red-eyed albino species, the "panda dragon" with transparent gill cover, the "Erlang god" with more eyes on the head, and other dragonfish with special appearance. These arowanas are not common. Under the special collection of people, their prices have risen because of their rarity and uniqueness
