(3) 魚缸大小(長*寬*高):
→60x40x40
(4) 魚缸種類(全草缸、半草缸、裸缸、海水無脊椎生態缸、汽水缸):
→半草缸(只有兩三根金魚藻點綴一下)
(5) 放不同批魚的間隔時間:
→
(6) 下缸步驟:對水方式→
對溫方式→
買來的時候,連同塑膠袋放置在魚缸上,等到半個小時後,剪一個洞,讓魚缸的
水慢慢混入塑膠袋,時間約20min
(7) 餵食頻率與數量:
→ 不定時,少量
(8) 換水頻率→一個月換1/3
換水方式→把缸內底部的髒東西吸出來後,再倒入放置三天以上的自來水
(9) 過濾設備(過濾器、濾材種類),燈具燈管及開燈時間:
→中型外掛式x1,小過濾桶x1,陽光幾何50W,每天約6hr
打氣機+細化器x1
(10) 有無底砂、哪種砂(顆粒大、中、小?)
→中顆粒美國細沙
(11) 有無使用浪板、有無定期吸底砂?
→無浪板,換水時順便吸底砂
(12) 換水週期,新水是否經過處理才加入?
→新水都放置三天以上,才加入
(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?
→無此現象
(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):
→無
(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):
→少量水草,無此情形
(20) 是否有定期用原缸水清洗過濾器?
→只有把過濾綿拿去擠一擠,把髒污擠出來,並未清洗
(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)
→其實問的是黑殼蝦,本來想養蝦,但是顧慮到養蝦成本頗貴,所以先養黑殼蝦測試一下
其實養的不只一次了,每次都買半兩(目測大概100隻左右),期間也都不是大量死亡,就是
每天死個三四隻,直到一個月後整缸只剩兩三隻存活,而且這兩三隻可以存活很久.剛買入
時有看到母蝦抱卵,可是入缸後,就很少有看到抱卵的情形.
缸內可供躲避的小東西頗多,黑殼蝦平常也都在美國細沙上面覓食,可見缸內沒有
攻擊性魚隻,但是我的魚缸可能水質偏硬,過濾器附近都是滿滿的白色水垢結晶,
不知道會不會有影響?
