鱼缸的水不用天天换,估计5天左右换一次就行了。
而且最好鱼缸里能有些水草。
再次就是不要给鱼喂太多东西吃,因为金鱼比较傻,会撑死!
家庭养金鱼,要将玻璃缸放置在近窗户通风又有阳光的地方。要注意放养密度,根据容器的大小,合理安排,宁可少养,不可多养。因为室内空气不大流通,养多了水易浑浊,容易造成金鱼缺氧而死亡。如有空气泵则可多养一些,发现金鱼有浮头现象则需开空气泵充氧,尤其是在夜间,更需要充氧。
家庭养鱼所用的饵料以活鱼虫最为理想,水质不容易坏,喂干鱼虫、人工合成颗粒饲料也可以。现在市场上有活鱼虫出售,不过要天天购买也很麻烦。对市场上卖的干鱼虫,要选比较新鲜的颗粒松散的喂鱼,不要买陈旧发霉的干鱼虫来喂养。人工颗粒饲料以用营养成分齐全的全价饲料为好,市场上有卖。
为了保持水质清纯,投饵量要严格定时定量,通常每日投饵1次至2次为宜,每次投饵量以在半小时内吃完为宜,饵料不要喂得太多。喂多了其害处有二:一是鱼吃饱了,代谢水平提高,耗氧量增加,容易引起金鱼缺氧窒息而死亡;二是饵料剩下,容易腐败发酵,使水质变坏,也会造成缺氧。其实金鱼是比较耐饿的,一两周不喂,也不会发生问题。
养金鱼保持水质清纯至关重要,要经常用乳胶管吸除积渣,把玻璃缸底部的粪便、残饵连同混浊水吸干净,然后徐徐地补进已放置一天的新水。倘若操作过程中出现水草浮起或假山被碰倒等情况,要及时恢复原状。
养鱼越久,沉渣积累越多。虽然每天清除,也不能全部清除干净。如果沉渣增多,影响玻璃缸的清晰度,就要彻底换水洗刷玻璃缸,才能保持水质清纯,便于观赏,也为金鱼保持优良的生活环境。
一般家庭所用的长方形玻璃缸因体积较小,不可多养,宜少不宜多。如在长40厘米、宽25厘米、高30厘米的容器内,可饲养5厘米至7厘米长的金鱼6尾至8尾。鱼体身长超过8厘米的成鱼,不宜在小型的玻璃缸中饲养,而需在豪华型的大玻璃缸或陶瓷缸中饲养,并配以小型充氧机备用,以防缺氧。以上放养密度只是参考,还要看水温的高低、鱼体的大小和水质的好坏来决定,不能机械行事。一般说来,鱼体大,要少养;冬季可多养,夏季要少养;水温低时可多养,水温高时要少养。
