水草是鱼缸中不可缺少的一员,它可以为水族世界增添色彩、协调景致,衬托鱼的美丽生动,同时对鱼的生长、繁殖有非常重要的作用。水草白天进行光合作用产生的氧气比它在夜间消耗掉的氧气量多,能在水中为鱼源源不断地提供氧气;饲料残渣和鱼的排泄物经一定时间后会被细菌分解,水草能吸收它们,保持水质清新;许多种金鱼或热带鱼要将卵产在水草茎叶上,有些刚孵出的仔鱼也要停留在水草上度过卵黄囊营养阶段,逐渐发育长大;有些鲤科、脂鲤科鱼喜食自己的卵,茂密的水草可保护受精卵免受吞食。 Aquatic plants are indispensable members of aquariums, which can add color to the aquarium world, coordinate the scenery, and bring out the beautiful and vivid fish. In the meantime, it plays a very important role in the growth and reproduction of fish. During the daytime photosynthesis of aquatic plants produces more oxygen than oxygen it consumes at night, providing oxygen continuously to the fish in the water; excrement from feed residues and fish can be broken down by bacteria after a certain period of time and aquatic plants can absorb them , Keep the water quality fresh; many species of goldfish or tropical fish to eggs in the stems and leaves of plants, some newly hatched larvae also stay in the water on the stage of yolk sac nutrition, and gradually grow; some Cyprinidae, carp Section fish eat their own eggs, dense plants can protect the fertilized eggs from swallowing.
