============================================
板友好,小弟剛接觸養蝦約1個多月,先前是虎
紋跟玫瑰混養,約22cm*14.5cm*11cm的空間,過濾系
統僅架設上部過濾,內部擺置為浮木莫絲片、莫絲屋
及藏小蝦用水草,有定期加硝化菌。溫控在24~26度
其實之前虎紋蝦就有陸續死亡的情況,死前狀況
為活動力低、常待在過濾抽水處的生化綿上,隔天就
會白白的死在那。
而前幾天剛買進6隻琉璃蝦,很開心的入缸後幾天
皆無恙,但前2天跟今天陸續死了2隻,死前情況是殼的
顏色變暗淡(紅色變暗紅),然後也有白化的現象。
小弟有努力的爬過文,畢竟不想再發生當時虎紋蝦
6隻全數陣亡的悲劇,在猜測是否為我的魚缸太小,蝦群
密度太高,加上都有在餵飼料(平均2天一次,量約半小
時內吃完),導致"氨"的濃度超過標準而中毒死亡,但水
族老闆又說蝦子在空間上的問題不大,注意擴大立體表面
積就好(所以我放不少浮木)
目前僅想得到上述氨濃度過高的可能,所以還希望板
友能提供看法,且若真的可能是氨濃度過高,也希望板友
能提供改善的辦法 (有注意過蒙脫石,但網友意見兩極)
以下有詳細的數據供版友幫忙診斷,謝謝!
PS:我蝦缸的樣貌:
http://ppt.cc/HwJx
=============================================
(1) 飼養魚(蝦)種及數量:
→ 原有:2隻小鼠魚、11隻成蝦(玫瑰*6、琉璃*5)、5隻小蝦(3周大)、一胎量幼蝦(3天大)
(2) 設缸時間,設缸多久放魚:
→ 一個半月前設缸
(3) 魚缸大小(長*寬*高):
→ 22cm * 14.5cm * 11cm(土表以上水深)
(4) 魚缸種類(全草缸、半草缸、裸缸、海水無脊椎生態缸、汽水缸):
→ 草缸
(5) 放不同批魚的間隔時間:
→ 設缸一個多月放進5隻琉璃蝦
(6) 下缸步驟:對水方式→ 每10分鐘將缸中水少量放入裝新進蝦的容器中
對溫方式→ 整個塑膠袋泡在缸中
(7) 餵食頻率與數量:
→ 約1~2天餵食一次,量為30分鐘內吃完為主
(8) 換水頻率→ 3~4個禮拜
換水方式→ 先以虹吸官吸取底層髒水以及沉澱物,再加入約1/3原水量的水
(9) 過濾設備(過濾器、濾材種類),燈具燈管及開燈時間:
→ 外部過濾器(放生化棉);LED-UV日光燈(早上8點開到晚上11點)
(10) 有無底砂、哪種砂(顆粒大、中、小?)
→ 珊瑚砂 + 大顆粒黑土(聽說比較多礦物質、且能酸化,開始一區一區換成黑土)
(11) 有無使用浪板、有無定期吸底砂?
→ 無浪板、僅在換水時吸底砂
(12) 換水週期,新水是否經過處理才加入?
→ 3禮拜換一次,新水為熱水高處衝下的自來水,有靜置約3天
(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?
→ 皆無
(14) 死魚的間隔、種類?
→
(15) 魚隻的食慾是否減退?
→
(16) 魚隻的活動情況(游泳頭上尾下,載浮載沉,異常群游等):
→
(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):
→
(18) 是否已下藥,下了什麼藥,劑量如何?
→
(19) 缸中水草狀況(生長停滯,藻類橫生,底部掉葉,爛葉等):
→
(20) 是否有定期用原缸水清洗過濾器?
→
(21) 有無加溫器、魚缸水溫?
→
(22) 請提供照片(非必須)
→
(23) pH值?(非必須)
→
(24) 補充(非必須)
→
