冬季金鱼头部下沉的预防

金鱼（细节）

新金鱼进入冬季的最大风险是温差和其他原因导致的头部下沉疾病。由于这种疾病的治愈率相对较小，因此预防尤为重要。冬季出售的金鱼，无论是在露天还是在鱼店，基本上都是从渔场的鱼屋出售的。因为鱼舍的水温很低，所以鱼的体质基本上是很差的。此外，经过长时间的停下来或少吃，转移到批发点销售，鱼商买卖，经过这么多波折，对鱼的体质更是雪上加霜，鱼也疲惫不堪。鱼友这个时候买的鱼最大的危险就是温差、温差和折腾带来的不适。在轻的情况下，鱼的所有部分都变黑，并且外部体表出现问题。在重的情况下，头部会跌倒或感冒。他们拒绝长时间进食，减肥，最后死亡。装袋时最好让鱼贩吸氧（足够24小时的氧气），回家后放在临时水箱或饲料箱旁边（不要移动或打扰），然后在24小时后开始浸泡和浇水（如果您直接从渔场购买，可以在浸泡后将鱼和水直接放入临时水箱，这样鱼会更快地适应）。这不仅让鱼有很长的时间来适应温度（首先适应室温，然后适应水温），还为鱼提供了一个中间过渡阶段，以缓解休息，这对新购买的鱼也非常有利。进入水箱一周后，水深不应超过20厘米，背鳍不应露出。在水中加盐，在一条小溪中吸氧，根据鱼的状况停止进食几天。一周后，观察鱼的状态（在本周的适应期内，如果可以喂食，最好喂食一些营养丰富的下沉式饲料），在游泳姿势正常、对食物的胃口正常的情况下，消化和体表正常（如果它仍躺在水箱里或拒绝进食，最好再延长几天进食方法和环境），然后在正常水深下正常进食。总的来说，这种方法是另一种非常简单的临时饲养和喂养方法，基本上适合冬季

Prevention of goldfish head sinking in winter

Goldfish (details)

The biggest risk of new goldfish entering winter is the head sinking disease caused by temperature difference and other reasons. Since the cure rate of this disease is relatively small, prevention is particularly important. The goldfish sold in winter, whether in the open air or in fish shops, are basically sold from the fish houses in the fishing grounds. Because the water temperature in the fish house is very low, the fish's physique is basically poor. In addition, after a long time of stopping or eating less, transferring to wholesale sites for sales, and fish merchants buying and selling, after so many twists and turns, it is even worse for the fish's physique, and the fish are also exhausted. The biggest danger of fish bought by fish friends at this time is the discomfort caused by temperature difference, temperature difference and toss. In the light case, all parts of the fish become black and there are problems on the external body surface. In the heavy case, the head falls or catches a cold. They refuse to eat for a long time, lose weight, and finally die. It is better to ask the fishmonger to take oxygen (enough oxygen for 24 hours) when bagging, put it next to the temporary tank or feeding tank after returning home (don't move or disturb it), and then start to soak and water after 24 hours (if you buy it directly from the fishing ground, you can put the fish and water directly into the temporary tank after soaking, so that the fish will adapt faster). This not only allows the fish to have a long time to adapt to the temperature (first adapt to the room temperature, then adapt to the water temperature), but also provides the fish with an intermediate transition stage to ease the rest, which is also very beneficial for the newly purchased fish. One week after entering the tank, the water depth should not exceed 20 cm, and the dorsal fin should not be exposed. Add salt in the water, take oxygen in a small stream, and stop eating for a few days according to the status of the fish. After a week, observe the status of the fish (during the adaptation period of this week, if it can be fed, it is better to feed some nutritious sunken feed), under the condition that the swimming posture is normal, the appetite for food is normal, and the digestion and external body surface are normal (if it is still lying in the tank or refusing to feed, it is better to extend the feeding method and environment for a few more days), and then feed normally at normal water depth. In general, this method is another very simple temporary rearing and feeding method, which is basically suitable for winter
