选择金鱼的六个注意事项

金鱼（详细介绍）

很多人都会养金鱼，有些人更注重把金鱼当作风水鱼来养，家庭养殖的一般目的是美化家园。金鱼的体色非常多，游泳姿势也非常漂亮，但我们如何才能买到健康的金鱼呢？

1、看看外观。如果你仔细观察，在玻璃缸里游泳的金鱼会发现一些问题。如果你在水中游泳时只摇摇头，不动身体，那就证明你营养不良，游泳累了，你的肚子不能鼓起来，你患上了鱼瘦病。结果发现，无论颜色多么美丽，它都不是优质的金鱼，表明它生病了，不健康。如果不仔细观察，还会出现头尾不均的情况，如鱼尾不均、尾巴歪斜：眼球大小不均、不标准，绒球鱼的两个绒球必须对称

2、看颜色

金鱼的颜色五颜六色，令人眼花缭乱。注意选择不能是灰色或黑灰色的黑色品种；猩红的品种不能是红色或黄色；有些红鱼像小胡萝卜，并不理想。有些鱼是半红半黑的，或者是红色的，有黑色的鳍和叶子。它们看起来很漂亮，但并不漂亮，因为它们会在短时间内变红，所以它们需要有预测能力

3、误解

市场上有很多种金鱼，如果你不小心，你就会进入误解。一些金鱼患上了“炸鳞病”，误以为自己买了珍珠鳞鱼。他们的腹部有水，很难治疗。采摘珍珠鳞片时，你应该看看身体的形状，有两个锋利的末端，像枣核。头部和尾部手柄不尖，这是不可接受的

4、看看身体形状

金鱼孵化后长成幼鱼，需要经过许多步骤。在运输过程中，难免会出现一些鱼鳍和鱼鳞容易撕裂脱落，背部和尾部的鱼鳍容易断裂开裂，腹部两侧的鱼鳞也容易脱落。特别突出的是，红黑鱼鱼鳞脱落后，鱼会经历皮肤的灰白色，这很难看，影响观赏。

5、金鱼有七种常见的疾病：①白斑病：幼鱼的尾巴和鳃盖上有白斑。②真菌病：鱼肚两侧易划伤部位出现白色菌丝。③白血病：鱼肚两侧有白霜。④鱼虱病：鱼虱就像人的虱子。⑤鱼鳞煎病：鱼的腹部有鱼鳞，两个鳃盖呈半红色，吻的下巴也呈红色。⑥轮虫病：患有这种病的鱼喜欢靠近边缘游泳。⑦浮头病：它的特点是脱离群体，头朝上，尾巴朝下，在水中轻微缺氧，尤其是在三伏天

6、观察尾鳞

对于有四条大尾巴的金鱼物种，鱼的尾鳍背部中间必须裂开，形成两条双下垂的四尾，游泳时美丽而悠闲。如果发现尾鳍后部中间没有裂纹，就像三尾前头型一样，是一种缺陷产品

当你选择你想要的金鱼时，你应该小心照顾它，这样金鱼才能展现出它的美丽来美化你的生活

Goldfish (detailed introduction)

Many people will raise goldfish, some pay more attention to raising them as geomantic fish, and the general purpose of family breeding is to beautify the home. The body color of goldfish is very many, and the swimming posture is also very beautiful, but how can we buy healthy goldfish

The goldfish swimming in the glass tank can pick out some problems if you carefully observe it. If you swim in the water only shaking your head and not moving your body, it is confirmed that you are malnourished, swimming tired, and your belly can not bulge, and you suffer from fish thin disease. It is found that no matter how beautiful the color is, it is not a high-quality goldfish, indicating that it is ill and unhealthy.

Some fish are half red and half black, or red with black fins and leaves. They look beautiful, but they are not beautiful, because they will turn red in a short time, so they need to have the ability to anticipate

3、 Misunderstanding

Where there are many kinds of goldfish in the market, you will enter the misunderstanding if you are not careful. Some goldfish suffer from "fried scale disease" and mistakenly believe that they bought pearl scale fish. They have water in their abdomen, which is difficult to treat. When picking pearl scales, you should look at the shape of the body with two sharp ends, like a jujube stone. The head and tail handle are not pointed, which is not acceptable

4、 Look at the body shape

After hatching, goldfish grow into young fish, it has to go through many steps. In the process of transportation, it is inevitable that some fins and scales are easy to tear and fall off, and the fins at the back and tail are easy to break and crack, and the scales on both sides of the abdomen are also easy to fall off. What is particularly prominent is that after the red and black fish scale off, the fish will experience the grayish white of the skin, which is very ugly and affects the viewing

5、 There are seven common pathologies of goldfish: ① white spot disease: there are white spots on the tail and gill cap of young fish. ② Mycosis: white hyphae appear at the easily scratched parts on both sides of the fish belly. ③ Leukosis: there is hoarfrost on both sides of the fish belly. ④ Fish lice disease: fish lice are like human lice. ⑤ Scale-frying disease: there are scales on the belly of the fish, and the two gill covers are half red, and the chin of the kiss is also red. ⑥ Wheelworm disease: fish with this disease like to swim close to the edge. ⑦ Floating head disease: It is characterized by being out of the group, head up, tail down, and slight hypoxia in the water, especially in the dog days

6、 Watching tail scales

For goldfish species with four big tails, the middle of the tail fin back of the fish must be split to form two double pendulous four tail, which is beautiful and leisurely when swimming. If it is found that there is no crack in the middle of the back of the tail fin, and it is like the three-tailed front head type, it is a defective product
