金鱼为什么打架？

金鱼也会打架。

金鱼是温顺的宠物鱼。我们经常发现他们在坦克里闲着，很安静。有时水箱表面没有波纹。很少有大鱼攻击小鱼和其他战斗情况。然而，很少出现并不意味着没有。据信，大多数主人都见过金鱼打架和被咬。金鱼生活在水中，有很强的领土感，很容易被忽视。通常，体长超过10厘米的金鱼具有一定的攻击性和占有欲。当然，这种攻击性只适用于同类。我过去不知道金鱼的这种习性。我曾经把一条大小相似的红背金鱼放进一个银红色鱼头的鱼缸里。人们发现这两条金鱼不和。银红色的头一直在追逐草金鱼，头不断地互相摩擦。这两条鱼的游泳姿势非常紧张和不安。第二天早上醒来时，我惊讶地发现鱼缸外有一具红背金鱼的尸体。银红色的头还是不错的，游泳的姿势也轻松舒适。所以我认为，这两条鱼应该是在争夺地盘，“新鱼”不能与“老鱼”竞争。在追逐和泼溅的过程中，他们从水里跳了出来，不幸从水箱里掉了出来。后来，为了验证他的猜想，三条大小几乎相等的金鱼被同时添加到相同大小的鱼缸中。结果，第二天早上，悲剧再次发生。其中一条最强壮的金鱼似乎躺在鱼缸外，而另外两条金鱼则在战斗中逐渐妥协，生活在平静中。当然，金鱼的这种行为与它们自己的习性和鱼缸的大小有关。鱼缸的大小与金鱼的数量直接相关。不要带着圆口的中小鱼缸，同时喂养三条以上的金鱼，因为狭小拥挤的空间会直接威胁金鱼的生存和健康。如果你想更具观赏性，饲养更多的金鱼，你必须选择中大型矩形玻璃水族箱。除了换水和清洁的麻烦，大型水族馆对金鱼的生存环境非常有利。而且，由于矩形水族馆有垂直的墙壁，没有折射和凸透镜效果，因此观赏效果也是最好的。在这种鱼缸中，可以饲养不同种类的金鱼，但最好确保金鱼的大小和长度基本相同，不要相差太大。同时，可以增加空气泵，以确保充足的氧气。小圆口鱼缸适合饲养一条或更少的金鱼。最好不要在现有金鱼的鱼缸中添加新的鱼。水质的好坏将直接影响金鱼的正常生长发育。换水的目的是去除水中的污垢（垃圾、鱼粪便、残留饲料和不新鲜的杂质），保持水的清洁，调节水温，增加水中的氧气，刺激金鱼的生长发育。在一些特殊的时候，金鱼会打架斗殴。例如，金鱼在怀孕和分娩期间的性情可能会发生很大变化，变得凶猛、好斗。因此，怀孕和分娩期间的金鱼应该放在单独的鱼缸中，以防止金鱼相互攻击

Why do goldfish fight?

Goldfish fight, too.

Goldfish are docile pet fish. We often find that they are idle and quiet in the tank. Sometimes there are no ripples on the surface of the tank. There are few big fish attacking small fish and other fighting situations. However, few occurrences do not mean none. It is believed that most owners have seen goldfish fighting and being bitten. Goldfish live in water and have a strong sense of territory, which is easy to be ignored. Generally, goldfish with a body length of more than 10 cm have certain aggressiveness and possessiveness. Of course, this aggressiveness is only for the same kind. I didn't know this habit of goldfish in the past. I once added a red-backed goldfish of similar size into a fishbowl with a silver red head. It was found that the two goldfish were at odds. The silvery red head was always chasing the grass goldfish, and the head was constantly rubbing against each other. The swimming posture of the two fish was very tense and uneasy. When I woke up the next morning, I was surprised to find the body of the red-backed goldfish outside the fish tank. The silver red head is still good, and the swimming posture is also relaxed and comfortable. So I think that the two fish should be fighting for territory, and the "new fish" can not compete with the "old fish". In the process of chasing and splashing, they jumped out of the water and unfortunately fell out of the tank. Later, in order to verify his conjecture, three goldfish of almost equal size were added to the same size of the fish tank at the same time. As a result, the next morning, the tragedy happened again. One of the strongest goldfish appeared to be lying outside the tank, while the other two fish gradually compromised with each other in the fight and lived in peace. Of course, this behavior among goldfish is related to their own habits and the size of the fish tank. The size of the fish tank is directly related to the number of goldfish. Do not take small and medium-sized fish tanks with round mouths and feed more than three goldfish at the same time, because the narrow and crowded space will directly threaten the survival and health of goldfish. If you want to be more ornamental and raise more goldfish, you must choose medium and large rectangular glass aquariums. In addition to the trouble of changing water and cleaning, the large aquariums are very beneficial to the survival environment of goldfish. Moreover, because the rectangular aquariums have vertical walls, no refraction and convex lens effects, the viewing effect is also the best. In this kind of fish tank, different kinds of goldfish can be raised, but it is better to ensure that the size and length of goldfish are basically the same, and not too different. At the same time, air pump can be added to ensure sufficient oxygen. The small round mouth fish tank is suitable for raising one or less goldfish. It is better not to add new fish in the tank with existing goldfish. The quality of water quality will directly affect the normal growth and development of goldfish. The purpose of changing water is to remove the dirt (garbage, fish feces, residual feed and stale impurities) in the water, keep the water clean, regulate the water temperature, increase the oxygen in the water, and stimulate the growth and development of goldfish. In some special times, goldfish will fight and fight. For example, the temperament of goldfish during pregnancy and childbirth may change greatly and become fierce and aggressive. Therefore, goldfish during pregnancy and childbirth should be kept in a separate fish tank to prevent goldfish from attacking each other
