1.检查鱼体各部位是否有虫害，观察有否烂鳍、口腐、穿孔、松鳞、红斑、颜色变异等。观察鱼是否逐渐消瘦，这是营养不良造成。观察鱼体是否水肿而腹部是否下垂，这是母鱼无法产卵所至，留在腹中腐烂。鱼体浮肿时会发展为松球病，这显然是内脏引起的。观察鱼体是否弯曲，原因往往是投药不当或过量引起的。观察眼球是否正常，如有异常，大部分是因内脏疾病引起的。不要发现太晚，到眼球塌陷时就无药可救。观察鱼鳃，是否正常张合，对死鱼及病鲤应将鳃盖拨开观察，有无变形、异物、寄生虫、黏液分泌过多等。

2.检查泳姿锦鲤健康时会向四面扩大游动，生病的锦鲤会离群独游，病证严重时会蹒跚游动、摇晃不定，甚至没有气力停止游动以至撞到池壁。锦鲤在鱼池的一角围成一环或以躯体摩擦池壁或池底，这表示鱼体上已经附有寄生虫，严重时锦鲤擦身、扇动背鳍及胸鳍，或跳跃。锦鲤如果耸立背鳍游泳，一般是神经系统患病的迹象。锦鲤以躯体弯弯曲曲游动是锦鲤异常的讯号。漂浮于水面静止不动是危险讯号。无法直立是丧失平衡感的状况，可能是鱼鳔出了问题，也可能是头部患有寄生虫，病态严重时锦鲤会乱游。

3.检查食欲锦鲤生病时食欲会减退。喂食时尽量观察情况，直至吃完。注意不要有吃剩的料沉底腐烂从而影响水质导致鱼病加速发生。食欲减退有很多原因，如缺氧、氨上升、水温变化、寄生虫附生、感染病毒、内脏疾病等。

4.检查粪便锦鲤粪尿状态也是锦鲤健康的标示。有时池水水面会浮现鱼粪便，这是消化不良的证明，应立即停食。比池水比重轻的粪便是不好的。锦鲤的粪便成白色明胶状时，是肠黏膜剥落的危险讯号，如果不立即医治会发生肠炎及穿孔病。
