夏季是金鱼生长发育的旺季。这个季节,金鱼活跃,很少得病。但气温高达37℃～38℃时,水温亦常高达30℃以上,此时要特别警惕缺氧和“烫尾”两大威胁。要做好防暑降温工作,主要措施是加深水位达35cm～40cm,金鱼可潜入温度较低的深层,尽量使水温控制在30℃以内。彻底清污、勤换水和遮盖遮光网或苇帘,可减慢水温升高,保持水中较高的溶氧量和抑制浮游植物的大量繁殖,是预防金鱼“浮头”和“烫尾”的有效方法。阵雨之后,即使原来的水不算过老,也要彻底换水。因雨水降入鱼缸表层,其温度较雨前缸水低,温度低的水要往底下沉,缸底水温高要往上升,如此上、下对流,使缸内污物也随着上、下翻
Summer season is the growth and development of goldfish season. This season, goldfish are active and seldom get sick. But when the temperature is as high as 37 ℃ ~ 38 ℃, the water temperature is often as high as 30 ℃ or above. At this moment, we should be especially alert to the two threats of anoxia and “hot tail”. To do a good job in sunstroke cooling, the main measure is to deepen the water level of 35cm ~ 40cm, goldfish can sneak into the lower temperature, try to make the water temperature control within 30 ℃. Thoroughly decontamination, frequently changing the water and cover the shading net or reed curtain, can slow down the water temperature to maintain a high dissolved oxygen in the water and inhibit the mass propagation of phytoplankton, is to prevent the goldfish “floating head” and “ Hot tail ”effective method. After the shower, even if the original water is not too old, but also completely change the water. Due to rain into the surface of the tank, the temperature is lower than the rain before the cylinder water, low temperature water to sink to the bottom, the bottom of the cylinder temperature to rise, so up and down convection, so that the dirt inside the cylinder with the upper and lower turn
