珍珠金鱼,别名珠鳞,体短腹膨,尖头尖嘴小眼睛尖尾柄。两头尖是珍珠金鱼体态特征,但珍珠金鱼主要特征还在于它具有沉淀石灰质的鳞片。珍珠鱼十分娇贵,如果你想自己繁殖培育优良品种的话,则饲养幼年珍珠鱼要格外认真。要使幼鱼接受足够的阳光,重视珍珠鱼灭杀病菌,以增强幼鱼的体质,要严格控制换水、喂食等。幼年珍珠鱼若用老水饲养,会影响幼鱼的生长,每日应吸出五分之一老水,兑入存放三天以上的同温新水,使幼鱼迅速的生长。幼年珍珠鱼需氧量较大,要尽可能放宽密度饲养,以免幼鱼缺氧。饲养幼年珍珠鱼的水体及深浅应掌握合适,太深增加幼鱼负担,太浅又容易烫尾,水深控制在幼鱼体高的5～10倍,随着幼鱼的成长而降低倍数,以水 Pearl goldfish, alias Pearl scales, body short abdomen expansion, sharp beak small eye sharp tail handle. Both tips are pearl goldfish body characteristics, but pearl goldfish main feature is that it has precipitated lime scales. Pearl fish is very delicate, if you want to breed fine varieties of their own breeding, then feeding young pearl fish to be extraordinarily serious. To make young juveniles receive enough sunlight, emphasis on pest fish kill germs, to enhance juvenile physique, to strictly control the water, feeding and so on. If young pearl fish are kept in old water, the growth of juveniles will be affected. One-fifth of the old water should be sucked daily, exchanged with fresh water stored at the same temperature for more than three days so that juveniles can grow rapidly. Juvenile pearl fish larger oxygen demand, as far as possible to relax the density of feeding, so as to avoid juvenile hypoxia. The juvenile pearl fish feeding water depth and depth should be appropriate, too deep to increase the burden of juveniles, too shallow and easy to hot tail, water depth control of juvenile body height of 5 to 10 times, with the growth of juvenile reduced times, with water
