金鱼身上有白色的絮状物

金鱼头上的白色絮状物是水霉引起的，水霉是伤口感染引起的，白色絮状体是菌丝体。这表明细菌已经侵入了身体，然后可能会出现溃疡，需要尽快治疗

主要原因是水温低，低于20℃，这经常发生在早春和冬末。你可以提高水温，然后将青霉素注入鱼缸，或者加入少许粗盐。患病的鱼每次可以在孔雀石绿或甲基蓝溶液中浸泡10-20分钟，几天后可以看到菌丝脱落。水霉菌主要与水质有关。换水时，应控制水温。每次都要换一部分旧水，以避免金鱼不适应。自来水不能直接使用。它需要暴露在阳光下或静置几天才能去除氯

There are white flocs on the goldfish body

The white flocs on the goldfish head are caused by water mildew, water mildew is caused by wound infection, and the white flocs are mycelium. This indicates that bacteria have invaded the body, and then ulcers may occur, which need to be treated as soon as possible

The main reason is that the water temperature is low, lower than 20 ℃, which often occurs in early spring and late winter. You can raise the water temperature, and then inject penicillin into the fish tank, or add a little crude salt. The diseased fish can be soaked in malachite green or methyl blue solution for 10-20 minutes each time, and the hypha can be seen to fall off after a few days. Water mold is mainly related to water quality. When changing water, the water temperature should be controlled. Every time, a part of the old water should be changed to avoid the goldfish not adapting. Tap water cannot be used directly. It needs to be exposed to the sun or left standing for several days to remove chlorine
