============================================
先謝謝上次各位大大的幫忙
最近發現魚有沉底的現象,網路上說半夜的沉底應該是正常現象
但這一兩天發現,有魚會在非半夜時段就沉底
雖然說他們還是會跑上來討飼料,不過這狀態還是蠻讓人擔心的
這些新同學是跟以往不一樣的店家買的
怕會不會是他們帶來了什麼不得了的東西
(上次的慘案讓人變得有點神經質阿)
=============================================
(1) 飼養魚(蝦)種及數量:
→8隻金魚(4隻元老,4隻新同學),2隻珠鱗
(2) 設缸時間,設缸多久放魚:
→大約三週前放新魚
(3) 魚缸大小(長*寬*高):
→兩呎缸(長60 cm;寬35 cm)
(4) 魚缸種類(全草缸、半草缸、裸缸、海水無脊椎生態缸、汽水缸):
→裸缸
(5) 放不同批魚的間隔時間:
→超過半年以上
(6) 下缸步驟:對水方式→
舀大概100 ml的水倒入袋中,等待約25~30分
重複三次後將塑膠袋斜放 讓魚自己游出來
對溫方式→
前30~40分鐘將裝魚的塑膠袋放入缸中,之後打開袋子開始對水
(7) 餵食頻率與數量:
→一天1~2次 中午和晚上
(8) 換水頻率→
一週一次,每次1/4~1/3缸
換水方式→
用風管把水引到至水桶,再用風管把新水導到魚缸裡
(9) 過濾設備(過濾器、濾材種類),燈具燈管及開燈時間:
→三層式上部過濾器
第一層兩塊白棉
第二層一塊白棉底下跟綠色生化棉
第三層珊瑚骨上鋪陶瓷環
(10) 有無底砂、哪種砂(顆粒大、中、小?)
→細的礫石底砂
(11) 有無使用浪板、有無定期吸底砂?
→無浪板;定期清部分區域底砂
(12) 換水週期,新水是否經過處理才加入?
→前陣子魚缸硝化系統不穩時,用加水站的水打氣約1天後加水
最近一次換水(4/30)是用打氣(加起來有打超過24小時)&自然曝氣(放室內)3天的水
(13) 現在魚缸的水是否白矇或偏綠?水面上汽泡是否許久不散?
→水算清澈而且缸邊沒有氣泡
靠近聞會有些微的味道
(14) 死魚的間隔、種類?
→無
(15) 魚隻的食慾是否減退?
→這兩隻看到人一樣會衝上來討食物,但不理他們一陣子後就會默默找位子趴著
應該食慾算正常
(16) 魚隻的活動情況(游泳頭上尾下,載浮載沉,異常群游等):
→這兩隻游了一陣子後,會默默的趴在底砂上,其他隻都是半夜才會沉到底部
(17) 魚隻體表黏液是否過多,有無發白區塊,或其他病徵(發黑、白點、縮鰭等):
→有縮鰭;好像有白點,不過看不太出來
(18) 是否已下藥,下了什麼藥,劑量如何?
→目前沒有,不過打算先下0.3%粗鹽再看情況
(19) 缸中水草狀況(生長停滯,藻類橫生,底部掉葉,爛葉等):
→無水草
(20) 是否有定期用原缸水清洗過濾器?
→有
(21) 有無加溫器、魚缸水溫?
→無
(22) 請提供照片(非必須)
