怎么判断斗鱼是不是生病了

当斗鱼昏昏欲睡或者身上长白点的时候，说明它生病了，这时候你要及时把它和其它的鱼隔离开来，因为这些病都是会传染的。^[1] 另外，如果宠物店里买不到药，你得到网上买。^[2]

步骤

查看斗鱼身上有没有生病的症状

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/a\/ab\/Tell-if-a-Betta-Fish-Is-Sick-Step-1-Version-3.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-1-Version-3.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/a\/ab\/Tell-if-a-Betta-Fish-Is-Sick-Step-1-Version-3.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-1-Version-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 看看斗鱼有没有褪色。生病的斗鱼会褪色甚至完全掉色。^[3]
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/9\/93\/Tell-if-a-Betta-Fish-Is-Sick-Step-2-Version-3.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-2-Version-3.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/9\/93\/Tell-if-a-Betta-Fish-Is-Sick-Step-2-Version-3.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-2-Version-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 观察鱼鳍。健康的鱼鳍是完整的，而生病的鱼鳍上面可能有洞或者裂缝。^[4]
   • 如果鱼鳍是被夹在鱼身上而不是像扇子一样展开来的，也说明斗鱼生病了。^[5]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/9\/99\/Tell-if-a-Betta-Fish-Is-Sick-Step-3-Version-2.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-3-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/9\/99\/Tell-if-a-Betta-Fish-Is-Sick-Step-3-Version-2.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-3-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 观察斗鱼有没有昏昏欲睡。斗鱼生病的时候明显没有平时活跃，一副病恹恹的样子。^[6]
   • 斗鱼生病的时候会躲在鱼缸下面不出来。^[7]
   • 温度太高或太低也会使得斗鱼没有精神，所以你要先调节好温度。

5. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/4\/48\/Tell-if-a-Betta-Fish-Is-Sick-Step-5-Version-2.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-5-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/4\/48\/Tell-if-a-Betta-Fish-Is-Sick-Step-5-Version-2.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-5-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 5 检查鱼身上有没有斑点。如果鱼身上有白色的小斑点，尤其是头、口部位，那么它可能得了白点病。^[9]
6. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/9\/95\/Tell-if-a-Betta-Fish-Is-Sick-Step-6-Version-2.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-6-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/9\/95\/Tell-if-a-Betta-Fish-Is-Sick-Step-6-Version-2.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-6-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 6 看看呼吸有没有异常。如果鱼儿不断地跑到水面上来呼吸，它也有可能生病了。^[10]
   • 鱼儿偶尔跑到水面上来呼吸是正常的，但是一直这样做就不好了。
7. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/6\/66\/Tell-if-a-Betta-Fish-Is-Sick-Step-7-Version-2.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-7-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/6\/66\/Tell-if-a-Betta-Fish-Is-Sick-Step-7-Version-2.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-7-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 7 看看鱼儿有没有在鱼缸里摩擦。如果鱼儿老是背着鱼缸摩擦或者抓鱼缸里的植物，说明它生病了。^[11]
8. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/5\/54\/Tell-if-a-Betta-Fish-Is-Sick-Step-8-Version-2.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-8-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/5\/54\/Tell-if-a-Betta-Fish-Is-Sick-Step-8-Version-2.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-8-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 8 看看鱼儿身体上有没有其它的变化，比如眼睛有没有鼓起来。^[12]
   • 如果鳞片立起来也说明它生病了。^[13]
   • 观察鱼鳃。如果鱼鳃一直合不上，说明它们肿起来了。^[14]

处理鱼儿便秘

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/3\/3e\/Tell-if-a-Betta-Fish-Is-Sick-Step-9-Version-2.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-9-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/3\/3e\/Tell-if-a-Betta-Fish-Is-Sick-Step-9-Version-2.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-9-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 看看鱼儿有没有浮肿。如果有的话，它有可能便秘了。^[15]
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/d\/d9\/Tell-if-a-Betta-Fish-Is-Sick-Step-10-Version-2.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-10-Version-2.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/d\/d9\/Tell-if-a-Betta-Fish-Is-Sick-Step-10-Version-2.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-10-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 断食几天。首先是给鱼儿断食几天，让它把食物彻底消化排空。^[16]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/2\/2c\/Tell-if-a-Betta-Fish-Is-Sick-Step-11.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-11.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/2\/2c\/Tell-if-a-Betta-Fish-Is-Sick-Step-11.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-11.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 给它喂活饵。断食几天后，一开始，先喂点活饵给它。^[17]
   • 你可以喂活的丰年虾或红虫。每次喂它吃两分钟的食物，一天可以喂两次。^[18]
4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/3\/3a\/Tell-if-a-Betta-Fish-Is-Sick-Step-12.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-12.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/3\/3a\/Tell-if-a-Betta-Fish-Is-Sick-Step-12.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-12.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 不要喂太多。便秘是因为你之前喂食太多造成的，所以等它身体恢复后，你喂的食物要比以前少一点。^[19]

检查鱼鳍或鱼尾判断是否真菌感染

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/7\/72\/Tell-if-a-Betta-Fish-Is-Sick-Step-13.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-13.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/7\/72\/Tell-if-a-Betta-Fish-Is-Sick-Step-13.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-13.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 检查鱼鳍或鱼尾有没有腐烂。^[20] 真菌感染可能会弄烂鱼鳍或鱼尾。.^[21]
   • 有些长尾巴的品种，比如半月斗鱼，它老是咬自己的鳍是因为鳍太重了，这种情况下，你除了要看看它有没有腐烂的鱼鳍，还要看看它有没有其它症状。
   • 另外，检查看看靠近鱼尾的地方颜色有没有变深。^[22]
2. 2 检查鱼儿身上是否有由真菌感染引起的白斑。这种病最明显的特征就是鱼儿身上长白斑，另外，鱼鳍会粘成一块一块的，鱼儿也没有平时那么活跃。尽管真菌感染和鱼鳍腐烂是完全不同的两种疾病，治疗方式却是差不多的。^[23]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/f\/f8\/Tell-if-a-Betta-Fish-Is-Sick-Step-14.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-14.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/f\/f8\/Tell-if-a-Betta-Fish-Is-Sick-Step-14.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-14.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 换水。先把鱼儿抓出来放在一个小容器里，然后把水全部倒掉，脏水会滋生疾病，所以一定记得给你的鱼儿提供一个干净的环境。^[24] 把鱼缸彻底清洗干净再放水进去。^[25]
   • 把漂白剂和水以1：20的比例进行混合，然后把混合物倒进鱼缸放一个小时，把假的植物和铲子也浸泡在里面，但是石头别放进去，因为它们会吸收漂白剂。^[26]
   • 清洗完了还要再冲洗几次。
   • 把石头加热至230℃以上，然后等石头冷却了再放回鱼缸里。^[27]
4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/c\/c6\/Tell-if-a-Betta-Fish-Is-Sick-Step-15.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-15.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/c\/c6\/Tell-if-a-Betta-Fish-Is-Sick-Step-15.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-15.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 使用药物消毒。你可以加一些四环素或氨苄青霉素在鱼缸里，加多少要视鱼缸大小而定，或者在包装上查看使用说明。^[28]
   • 你还可以在水里加入真菌消除剂，这会阻止水里真菌的生长。^[29]
   • 如果你的斗鱼已经感染真菌了，而且它也不喜欢四环素或氨苄青霉素的味道，那么你就给它加一些真菌消除剂。^[30]
5. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/9\/96\/Tell-if-a-Betta-Fish-Is-Sick-Step-16.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-16.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/9\/96\/Tell-if-a-Betta-Fish-Is-Sick-Step-16.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-16.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 5 重复这个过程。每三天换一次水，每次换完水记得把药物加进去，一个月后，当斗鱼明显好转的时候，可以停止加药。^[31]
   • 检查真菌感染的白斑和其它症状是否消失。如果消失，就加入一些斗鱼专用的杀寄生虫药来消灭真菌。^[32]

应对丝绒病

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/5\/5d\/Tell-if-a-Betta-Fish-Is-Sick-Step-17.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-17.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/5\/5d\/Tell-if-a-Betta-Fish-Is-Sick-Step-17.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-17.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 用手电筒照鱼。手电筒的光可以帮你看清鱼鳞上有没有金斑或锈斑，生了丝绒病的鱼儿还会昏昏欲睡、胃口不佳或者不断地在鱼缸或其它物体上摩擦自己，还可能有鱼鳍缩紧现象。^[33]
   • 在水中加入盐或水质改善剂可以杀死寄生虫。^[34] 在9.5升的水中加入一茶匙盐，同时在3.8升水中加入一滴水质改善剂，不要一打开鱼缸盖子就加，每次都要换完水才加，另外，水质改善剂的用量还要具体查看使用说明，不能一概而论。^[35]
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/d\/d3\/Tell-if-a-Betta-Fish-Is-Sick-Step-18.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-18.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/d\/d3\/Tell-if-a-Betta-Fish-Is-Sick-Step-18.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-18.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 使用“鱼救”。这种药治疗丝绒病是非常有效的，因为它含有两种药剂。这种药物的用量是每10升水加入3滴。^[36]
   • 你还可以使用一种叫做“黄粉”的药物来治疗。^[37]
   • 持续治疗直到这些症状消失为止。
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/e\/e5\/Tell-if-a-Betta-Fish-Is-Sick-Step-19.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-19.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/e\/e5\/Tell-if-a-Betta-Fish-Is-Sick-Step-19.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-19.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 处理鱼缸。你在隔离生病的鱼的同时也要处理一下鱼缸，因为这种病会传染的。^[38]
   • 为了隔离生病的鱼，你要把它移到另外一个鱼缸并装入干净水，并且两个鱼缸都要好好清理。

治疗白点病

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/b\/b0\/Tell-if-a-Betta-Fish-Is-Sick-Step-20.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-20.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/b\/b0\/Tell-if-a-Betta-Fish-Is-Sick-Step-20.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-20.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 看看鱼儿身上有没有像盐粒一样的白点。斗鱼得白点病的时候身上会出现白点，鱼鳍会缩紧，没精打采，食欲减退。^[39]
   • 跟丝绒病一样，只要你正确处理水质，这种病也是可以预防的。^[40] 在9.5升水中加入一茶匙盐，水质改善剂的使用可以参考使用说明。^[41]
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/2\/29\/Tell-if-a-Betta-Fish-Is-Sick-Step-21.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-21.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/2\/29\/Tell-if-a-Betta-Fish-Is-Sick-Step-21.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-21.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 提高水温来治疗白点病。如果你的鱼缸是一个大型的混养鱼缸，你可以把水温加热到30℃来杀灭寄生虫；但是如果你的鱼缸比较小，你就不能加热，因为一不小心你可能会把鱼儿给烧死。^[42]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/3\/37\/Tell-if-a-Betta-Fish-Is-Sick-Step-22.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-22.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/3\/37\/Tell-if-a-Betta-Fish-Is-Sick-Step-22.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-22.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 换水并清理容器。关于如何净化水质，我们在第三部分已经提到过了，这里就不再赘述。^[43] 如果鱼缸比较小，就先把鱼儿捞出来，清洗干净，再把鱼缸里的水加热到30℃，最后再把鱼儿放回去。^[44]
4. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/5\/53\/Tell-if-a-Betta-Fish-Is-Sick-Step-23.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-23.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/5\/53\/Tell-if-a-Betta-Fish-Is-Sick-Step-23.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-23.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 4 处理水质。在把鱼儿放回鱼缸之前，先把盐和水质改善剂放进去，这样做可以预防新换的水滋生其它的寄生虫。^[45]
5. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/b\/b9\/Tell-if-a-Betta-Fish-Is-Sick-Step-24.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-24.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/b\/b9\/Tell-if-a-Betta-Fish-Is-Sick-Step-24.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-24.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 5 加入“白点净”。这种药物的用量是每5升水加入1毫升，每天都要用药直到鱼儿彻底痊愈，它会有效消灭寄生虫。^[46]
   • 如果没有“白点净”,你也可以少量地使用“鱼救”。^[47]

治疗鼓眼病

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/8\/8d\/Tell-if-a-Betta-Fish-Is-Sick-Step-25.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-25.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/8\/8d\/Tell-if-a-Betta-Fish-Is-Sick-Step-25.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-25.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 看看鱼儿的眼睛有没有鼓起来。鼓眼病的主要症状就是眼睛突出，但有时候这种症状也会伴随其它疾病发生。^[48]
   • 比如，鱼儿得了结核病眼睛也会突出来的。^[49] 如果真的是结核病，鱼儿就有可能没救了。^[50]
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/8\/80\/Tell-if-a-Betta-Fish-Is-Sick-Step-26.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-26.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/8\/80\/Tell-if-a-Betta-Fish-Is-Sick-Step-26.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-26.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 换水并清理鱼缸。得了鼓眼病的鱼儿需要呆在干净的鱼缸里，所以你要定期给它换上干净水。^[51]
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/5\/50\/Tell-if-a-Betta-Fish-Is-Sick-Step-27.jpg\/v4-460px-Tell-if-a-Betta-Fish-Is-Sick-Step-27.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/5\/50\/Tell-if-a-Betta-Fish-Is-Sick-Step-27.jpg\/v4-728px-Tell-if-a-Betta-Fish-Is-Sick-Step-27.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 使用氨苄青霉素。如果情况不是很严重，你可以在每次换水的时候在鱼缸里加入氨苄青霉素，每三天加一次直到鱼儿的这个症状消失。^[52]

建议

• 如果你认为鱼儿很痛苦，你可以帮它实施安乐死，但是一定要搞清楚，不要让鱼儿因为一点小毛病而冤死。
• 鱼儿变色的时候不要太紧张。大多数斗鱼身上的大理石纹都会变色，大理石纹的变化是从鱼儿身上某一处开始然后蔓延到全身的的。如果鱼儿生病了，它也会变色，但这种变色是一下子完成的，而且身上的颜色变得比以前苍白，这说明鱼儿可能压力太大。如果鱼尾被磨破了或者鱼鳍腐烂了，伤口会变成红色或黑色。

警告

• 有的症状出现时并不代表鱼儿生病了。如果鱼儿没精打采的，有可能是温度太低造成的；如果鱼鳍上有裂痕，那有可能是什么尖锐的东西刺伤的。不要一有状况就盲目地给鱼儿用药，你可以再观察一下看看有没有其它症状出现。
• 当心鱼结核病，这种病是会传染的，甚至是致命的，并且很有可能传染给人类。^[53] 鱼儿生病的症状有精神不振、鼓眼睛、骨骼变形或脊椎弯曲；而人生病的症状是感染细菌的地方会有大的红色肿块。如果你怀疑自己感染了鱼结核病，赶紧去看医生并跟医生说明你养鱼了，以免医生误诊。
• 斗鱼有的病是治不好的。比如，水肿就是斗鱼感染的一种致命的疾病，如果你从鱼儿的头顶看下来，它的鳞片是立着的而不是顺着的，那么它就是水肿了，生了这种病的鱼儿要和其它鱼儿隔离开来，因为水肿是无法治愈的。
