金鱼选择技巧

金鱼（细节）

金鱼在我们的生活中并不奇怪。从花鸟市场到路边摊，都有卖金鱼的。许多人会抱怨金鱼不容易喂养。事实上，这与金鱼的基本健康有关。选择健康的金鱼将对今后的养殖有很大帮助。那么如何选择金鱼呢

1、看外观

在玻璃缸里游泳的金鱼，如果你仔细观察它，可以找出一些问题。如果你在水中游泳时只摇头不动身体，那就证明你营养不良，游泳疲劳，肚子鼓不起来，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。从体型上看，金鱼在孵化后成长为幼鱼，需要经历许多步骤。在运输过程中，不可避免地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，与三尾前头型类似，则为缺陷产品

7、有哪些金鱼？

金鱼的分类很复杂。根据一般分类，金鱼有200多个不同的品种，主要分为三类：草类、文类和卵类

草科：长而侧身、与野生鲫鱼相似的属于这一类。它主要包括各种颜色的鲫鱼和带球的红鲫鱼

温氏：体型和背鳍凸起的都属于这个科。它主要包括各种颜色的蛛形纲动物、蛛形纲、鳍状肢、珍珠、高头类、狮子头类、龙眼等。

蛋科：身体短而凸，没有背鳍的属于这个科。主要有水泡、虎头、红蛋、朝天龙等。大多数饲养者根据金鱼的外表来选择金鱼。事实上，选择金鱼最重要的是健康和活力。饲养员应该清楚地了解，以免在饲养过程中遇到麻烦
