在我们决定养宠物之前，我们总会遇到这样或那样的疑问。尤其是对于刚开始养宠物的家庭来说，选择一只还是两只都可能是一个棘手的问题。这篇文章就要探讨一个与之相关的问题：养了2条鱼是不是不好。

首先，让我们来了解一下为什么有人会提出这个问题。在某些情况下，人们认为单独养一条鱼更为合适，因为它可以得到更多的关注和个性化的照顾。当你只有一个鱼时，你可以精确地控制水质、温度以及饲料，这样你的鱼将享受到最优质的生活环境。而如果有两条或更多的鱼，它们之间可能会相互攻击，甚至因为食物不足而争斗不息。

然而，对于许多人来说，拥有多条鱼并不是坏事。实际上，有时候多数水族箱中的生物能够相处得很好，只要它们足够大，并且被正确地引入到同一个环境中。此外，如果你对水族知识有一定的了解，并能提供适当的条件，那么多条小朋友也能共同活跃在同一个美丽的小世界里。

那么，我们该如何确定哪种方式对我们的家庭更好呢？这取决于你的目标和能力，以及你准备投入多少时间和资源去维护你的水族箱。如果你只是想简单地欣赏一下家中的生物生态系统，那么可能单独养一条较大的或者一些较少需要特殊照顾的小型冷水淡水魚类就会是个不错的选择。但如果你想要创造一种更加丰富、多彩、互动性的观赏体验，那么带着孩子一起学习如何管理两三只不同的淡水或海洋鱼类，也许就是更好的教育方法之一。

此外，与其他宠物不同的是， fishes are relatively low-maintenance pets. They don't require the same level of interaction or training as dogs or cats, and they can be a good choice for busy families or those who live in small spaces. However, this doesn't mean that you should neglect your fish entirely. They still need regular care and attention to thrive.

If you do decide to get two fish, it's important to choose species that are compatible with each other. Some fish may not get along at all, while others may coexist peacefully. Researching different types of fish and their personalities can help you make an informed decision about which ones would work well together.

Another thing to consider is the size of your tank. A larger tank will give your fish more space to swim around and reduce the likelihood of them fighting over food or territory. It's also important to remember that every time you add a new fish to the tank, it increases the bioload on your filter system.

In conclusion, whether having two fish is "bad" depends on many factors including your lifestyle, experience level with aquariums and what kind of environment you want for both yourself and your children when learning how best take care these beautiful creatures we call home pets - our aquatic friends! So before making any final decisions always weigh up pros & cons carefully so as not regret later down line!
