Most marine aquarium hobbyists want to provide as naturalistic and stress-free an environment as possible for the fish and other livestock in their care, so they’re careful to maximize water quality, offer nutritious foods, promote compatibility among tankmates, aquascape appropriately, and so on. In other words, they put a lot of thought into what’s going on里面水族馆。但是发生了什么事外部坦克？
在某些情况下，非常认真维护的水族馆仍然可能包含压力大的鱼，因为各种外部影响甚至可能不会出现爱好者，尤其是如果坦克房屋自然而然地开始使用的物种。这是我头顶上的四个：
1）振动
尝试这个小实验：站在水族馆的房间的另一侧，大喊，哨子或大声拍打您的手，同时观察鱼。接下来，脚踩在地板上，仍然关注您的piscine宠物。大喊，哨子或拍手对鱼的行为几乎没有影响，但sto脚使他们冲着掩护。
对此的解释是，空气中产生的更高的声音在越过空气/水接口方面做得很好，因此，鱼类往往不会被鱼类注意到。另一方面，沿着实心表面传播的低频振动肯定会转移到水族馆并被鱼毛感觉。
While many fish seem to grow accustomed to constant low-level vibrations, such as that produced by a submersible return pump, they’re apt to be stressed by sudden, intermittent vibrations—such as the aforementioned stomp, slamming doors, the thumping bass of stereo speakers, or the infernal revving of your neighbor’s ’72 Chevy Malibu engine.
2）不自然的房间照明
在自然界中，鱼类受到可预测的白天/夜间周期的影响，并逐渐变化。在鱼完全处于黑暗状态或不断打开灯的情况下，突然打开房间的灯光可能会非常令人吃惊和压力，捕鱼。理想情况下，您的水族馆应位于一个不太可能成为问题的房间中。否则，您需要注意这种压力源，也许只需将房间的灯打开，直到您准备好将其称为夜晚。
3）不可预测的运动
在水族馆附近的某种程度的人类活动是不可避免的，但应避免运动过多，尤其是突然的，不稳定的运动。Remember, as far as aquarium fish are concerned, something unfamiliar moving near the tank could be a predator fixing to eat them or a competitor out to take their resources, so they’ll stay in fight-or-flight mode when there’s too much activity nearby.
4）室温波动
当今潜水的水族馆加热器使设置和保持所需的水温非常容易，但是如果房间的气温急剧波动，则水箱中也可能发生不可接受的变化。这通常是在缺乏中央空调的房屋中温暖的季节中的一个问题。如果遇到此问题，则可能会安装水族馆冷却器或窗户空调单元。
5）幼儿
正如任何有水族馆的父母都知道的那样，幼儿可能会造成上面提到的许多压力 - 踩踏，反复打开和关闭灯，撞门，敲门，敲击水族馆玻璃，将鱼从水箱的一端追逐到鱼。另一个，等等。Since we don’t want to make our aquariums completely off limits to kids—and since most states forbid the sale of children (as it turns out)—the best option is to establish aquarium “ground rules” for youngsters (no running, fighting, throwing of toys, tormenting of fish, etc.) and supervise them very closely whenever they’re in the vicinity of the tank.
