============================================
養魚新手請多指教orz
兩週前新設缸,養水一週後下試水的極火蝦六隻,到現在只剩一隻存活...想請問大家我的缸出了什麼問題?
=============================================
(1) 飼養魚(蝦)種及數量:
→目前極火蝦*1、蘋果螺*2
(2) 設缸時間,設缸多久放魚:
→養水(加水穩和硝化菌,開外掛跑)一週
(3) 魚缸大小(長*寬*高):
→22*15*17cm小缸
(4) 魚缸種類(全草缸、半草缸、裸缸、海水無脊椎生態缸、汽水缸):
→有水蘊草*1、金魚藻*2、莫斯一片
(5) 放不同批魚的間隔時間:
→極火蝦六隻同時下
(6) 下缸步驟:
→對溫15分鐘,無對水
(7) 餵食頻率與數量:
→下蝦後兩天放三顆沉底飼料,蝦有吃,剩下一點點殘留我有夾走
(8) 換水頻率→設缸後兩週有換1/3水
換水方式→無曝氣自來水加一點水穩,以滴管滴入,滴完後補充一點硝化菌液
(9) 過濾設備(過濾器、濾材種類),燈具燈管及開燈時間:
→外掛,檯燈光照每天10小時左右
(10) 有無底砂、哪種砂(顆粒大、中、小?)
→大磯砂
(11) 有無使用浪板、有無定期吸底砂?
→換水前有吸一點
(12) 換水週期,新水是否經過處理才加入?
→自來水只加水穩和硝化菌液
(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?
→無,水看起來很清澈
(14) 死魚的間隔、種類?
→下蝦第二天死一隻,第六天死三隻,第七天死一隻
(15) 魚隻的食慾是否減退?
→無,會啃莫斯和搶飼料
(16) 魚隻的活動情況(游泳頭上尾下,載浮載沉,異常群游等):
→白天躲水草,晚上會出來逛大街
(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):
→無
(18) 是否已下藥,下了什麼藥,劑量如何?
→無
(19) 缸中水草狀況(生長停滯,藻類橫生,底部掉葉,爛葉等):
→除了莫斯有一塊光照不到的地方有點發黃,其他水草都長得很茂密
(20) 是否有定期用原缸水清洗過濾器?
→無
(21) 有無加溫器、魚缸水溫?
→無
(22) 請提供照片(非必須)
→
(23) pH值?(非必須)
→
(24) 補充(非必須)
→
一開始下蝦時有點驚慌飛游,第二天死了一隻,後來看起來蝦群算是穩定下來,晚上會啃莫斯和吃飼料。
第六天週日,我剛好前兩天不在,週日回來就看到死了三隻,都死在脫下的殼旁邊,但看起沒被攻擊。
我猜可能這兩天沒開檯燈,雖然是放窗邊有一點日照,但兩天都是陰天,可能光照不足水草造氧少導致溶氧不足?
第七天死蝦也剛好是剛脫殼,挾起屍體時是軟的,是蝦子脫殼後特別脆弱到容易死亡嗎?
目前剩下一隻...活動力感覺還可以,也有吃我給的飼料。
綜合以上所述,是蝦子脫殼後太脆弱,還是我硝化系統尚未建立好?接下來除了繼續讓外掛跑,還需做什麼改善呢?
先謝謝了orz
