最近邻居老王的金鱼眼睛蒙了层白膜，游起来像戴了雾霾眼镜，急得他直拍大腿。这种"鱼蒙眼"病其实很常见，水质差、打架受伤、细菌感染都可能让鱼眼糊上白雾。别慌，我整理了水族老手们亲测最快的法子，分轻重两种情况解决，照着做九成鱼儿能救回来！

一、轻度蒙眼：水质调理法（3-5天见效）

当鱼双眼同时泛白（像白内障），基本是水质中毒的警报。

1. 紧急换水：每天换1/4困过的水（自来水晾2天除氯），连换3天。注意水温必须和原缸一致，温差超2℃会雪上加霜。

2. 加温促代谢：用加热棒缓慢升温，比原水温高3℃（例如28℃升到31℃），加速排毒。

3. 下盐抑菌：每升水加3克无碘盐（约矿泉水瓶盖半盖），浓度别超0.5%。盐别直接撒！先用杯子化开再倒进缸。

二、重度蒙眼：外伤感染急救（1周控制）

如果只有单眼浑浊或带血丝，多半是撞伤、打架后感染。

Step1 隔离治疗

捞病鱼到小缸（原缸水+新水1：1），爆氧泵必开！

Step2 药物选择

黄粉药浴：10升水兑0.1克黄粉（牙签尖大小），泡4小时/天

青霉素强化：10升水加8万单位注射液（1支80万单位的用1/10）

Step3 患处直击

棉签蘸红霉素软膏轻涂鱼眼，涂完离水停留10秒再放回（避免药膏遇水化）

警告：千万别用高锰酸钾！浓度误差分分钟毒翻鱼

三、防复发秘诀：养护习惯定胜负

1. 过滤棉每周洗：脏棉藏菌超马桶，拆开搓洗比换水更重要

2. 尖锐装饰全清：假山、塑料水草划伤鱼眼是蒙眼元凶

3. 混养要谨慎：雷龙、斗鱼等猛鱼必须单养，打架伤眼难根治

4. 维生素食补：每周喂1次胡萝卜薄片或螺旋藻饲料，增强角膜韧性

蒙眼初期（白雾未肿胀）靠"换水+温盐"组合拳大多能挽回，拖到眼球凸出再治就难了。记住核心公式：清洁水质=防病根基，快速隔离=救命关键。养鱼老手常调侃："蒙眼别问百度，先测水质氨氮值"。备个小隔离缸、黄粉、加热棒，鱼命关天时比啥神药都靠谱！
