室内装饰, 金鱼:穿着美丽外衣的鲫鱼

金鱼实际上是一类人工驯养的鲫鱼。大约2000年以前,中国的古人就开始养殖银鲫(学名为Carassius gibelio),作为食物和观赏鱼。随着时间推移,基因突变和人工选择使银鲫身上出现了橙、红、黄等颜色,改变了其沉闷乏味的形象,也造就了我们今天看 到的多姿多彩的金鱼。17世纪的时候,金鱼传到欧洲,并于19世纪50年代来到美国。




虽然不属于野生的物种,金鱼却时不时在北美的池塘、湖 泊和溪流中出现。许多研究者认为,这些金鱼或者是被丢弃到水体中,或者是从洗手间冲水马桶里死里逃生出来的。许多大得不寻常的金鱼----正如马丁钓到的 这条----基本上都是在户外池塘中发现的。不过,金鱼专家说,用大鱼缸就能养成大金鱼的想法是非常不现实的。
