第一个问题就是鱼缸的水质问题,我们是否存在有突然间大量换水,或者鱼缸水温大幅波动的问题,如果出现了这两种情况,我们要去加以调整,水温问题我们可以快速升温,如果是大幅度换水的问题,不好意思,停食观察吧,什么时候鱼儿有食欲了,鱼儿适应水质了再说。
第二个问题就是受到了惊吓,这个我们通过鱼儿的状态是能够观察到的,比如说七彩神仙鱼可能黑体,龙鱼可能趴缸,看到主人急于找地方躲藏,那种顾头不顾腚的游姿,如果我们还看不出来的话,只能证明平时我们观察鱼儿太少了,好好补课吧。
第三个问题就是前一天吃多了,再瘦的观赏鱼如果吃多了肚子不消化也是会鼓起来的,肚子胖和肚子胀,完全是两个概念,即使是肚子很大的金鱼,如果是吃多了,它也会通过其他的肢体语言告诉你,比如说毫无进食欲望的金鱼是不可能存在的,游姿上可能是失漂的,肚子方起来了和正常的圆形是不一样的,等等吧,这个就看个人的观察能力了。
