参考译文

许多人把小鱼当宠物养。他们把鱼养在鱼缸里。鱼缸是由透明玻璃制成的。人能透过玻璃看到鱼缸的里面，也就可以欣赏鱼了。

鱼需要空间。它们不能太拥挤。鱼呼吸时需要氧气。鱼从鱼缸的水中获得氧气。养鱼需要充足的水，所以鱼缸的大小很重要。

许多人会把对鱼有好处的小草放进鱼缸里。它们向水中释放氧气。植物在其他方面也有用处。鱼可以咬这些植物，它们可以躲在植物中睡觉、产卵。

植物需要阳光。大多数鱼也需要。鱼缸可以放在窗户旁。这样，它就可以照到阳光了。窗户会让冷空气进来。鱼缸里的水也会因此而变得很冷。因为冷水会冻死鱼，热水会烫死鱼，所以温度必须适当。

鱼得始终待在水里。有些鱼跳得很高，它们会跳到鱼缸外。所以鱼缸应该加盖。这样鱼就跳不出来了。

鱼需要食物，人们应该每天喂食。喂得太多对它们不利。剩下的食物会沉到缸底，从而使水变浑。但鱼也应该得到适量的食物，这些食物应该在10分钟内吃完，且没有剩余。如果做到这一点，说明食物的量正好合适。
