I have discovered a disease (only found in certain clown fish spp). The only observable symptom is that every now and then, the fish will spiral (in a tight vertical cycle) in an uncontrolled manner (this appears to happen more often when it is frightened). The disease does not seem to be very contagious. The fish may die within a day but most survive indefinitely for up to weeks without feeding. The fish becomes inactive and rest or even lay on tank bottom, sometimes on its side. The entire fish body surface appears intact and healthy. The disease does not respond to treatment against bacterial infection or protozoan infection. Anyone has any idea? Sorry, I can';t type chinese yet but I am working on it though.

maybe you can reduse the air content of sea water.

測量NO2還有提升溶氧(打氣)並提供您的缸子照片上來
Dear Jeremy, thanks for the advice but I can assure you the disease has nothing to do with DO or the toxicity of NO2 or even NH3. I have monitored these. From the batch of 100 clown (Clarkii Clown), so far 6 suffer the diesease (1 shortly after arrival (in quarantine tank) and the rest at different time within a period of 6 weeks) and 3 still survive, isolated from the rest of the batch.
If no one has discovered the disease or named it, I would name it as "Spiral to Death Disease Syndrone", Just kidding! But sadly, this appeared to be the case.
I would assume that this is related to poisoning or toxic effects of pollutants (such as NO2 or NH3) but all other fishes (more than 20 spp including angels, groupers, damsels, sand perch, pseudo-chromis, blennies, gobies, and even tomato clowns, percula clowns and saddle-back clown(A. polymnus)) in the 4000L system remain unaffected by the disease and water quality has been reasonably good.

事實上海水魚的疾病我們能夠了解甚至治療的部分真的是很少,但是我仍很有興趣想了解一下您的病例,但是小弟的英文實在不怎麼樣,雖然使用過dr.eye仍有少數文句無法確認合理的譯文,我請河馬兄幫我翻,並儘可能的找出病因與解決方法....

我發現一種病 (只發生在某些小丑魚品種). 唯一可見的症狀是, 有些時候, 魚會一直無法自主控制的打轉, 而且是上下轉 (也常發生在魚受驚的時候). 此病在魚之間似乎不太互傳. 魚可在一日內死亡, 但也有可能拖上幾個禮拜完全不進食. 魚會無力的在缸底休息, 有時會側一邊躺. 魚體表無傷痕且看起來健康. 此病對bacterial 跟 protozoan感染的治療無反應.
請問有沒有其他意見可提供? 對不起, 我無法中打.

赤子, 謝謝您的建議, 但是我可以確認此病跟溶氧或亞硝酸或氨沒有關聯. 這些我一直都有在監測. 其中一批約100隻小丑裡 (克氏小丑), 有6隻有此病. (六隻裡, 一隻運抵後隨即死在隔離缸, 其餘五隻在6個禮拜內陸續死亡)
如果還未有人發現此病, 我可能會稱做 “Spiral to Death Disease Syndrone” (轉圈致死症候群). 冷到了. 但不幸的, 這也是事實.
我猜這可能跟某種毒性或汙染有關 (例如NO2或是NH3). 但是在同一套4000公升系統裡的其他20多種魚種則沒有類似症狀, 並且水質也持續保持著.

那些魚種各位就自己去看了, 我對魚的台灣俗名也不甚了..........

河馬兄萬分感謝.....^^
坦白講我很難肯定這到底是什麼病因,我只能就您的敘述去做分析與判斷,首先可以確定的是此病症与寄身蟲,或者是細菌,病毒關聯性很低,大多數魚類相關的病原體都可能在同種或者是異種中傳播,且體表通常也會有明顯的症狀,且由您敘述的文字當中可以發現您應該是屬於比較進階的魚友,基本的環境要素您也都有長期的監控與掌握,所以這個病因也應該是與環境無關,唯一的可能性就是來自於長途運輸的傷害....
運輸期間魚類生存在小水體當中,其氨與二氧化碳的代謝仍然會持續著,雖然袋中有高濃度的氧氣分壓來提供魚類所需的氧氣,但是節節升高的氨與二氧化碳卻與血球有更高的親合力,再進入危險濃度的時候則可能進一步的造成魚類組織缺氧,缺氧到達某種程度後則可能造成不可回復的傷害,這些傷害可能會馬上致死或者延遲一段期間,由您說明的行為症狀(魚會一直無法自主控制的打轉)我猜測可能是神經系統的傷害.....
站上贊助商曾經說明過一次國內運送小丑的案例,某種品種的小丑全數在到達前死亡,同一批輸送的其他品種小丑還有一些神仙魚卻全數存活...原因不明...
如果說一批100隻的小丑長途輸送,只損失六隻,個人認為應屬合理的損失範圍....
