這篇我來個自問自(摸索)答好了...
縮鰭的2隻紅雙劍撐了幾天還是走了,
因為想繼續養紅雙劍,這幾天不斷的思索我還能如何改善。
歸納幾點思考,再請各位前輩指教了:
1. 可能是餘氯的問題:
經查有一說台北的水,氯的添加是別的縣市的4倍,
因此我決定將新水「加鹽+曝氣1天」改為「加鹽+曝氣2天」,比較保險。
2. 可能是溫差變化過大:
但因為換水都用滴流,大約1公升水30分鐘,故此因素應可排除。
3. 可能是溶氧不足:
為了增加魚的活動空間、降低水流聲響及噴濺,
我過去水位一般都加得比較高(離缸頂僅3~4cm),
如此一來外掛流下來的水跟空氣接觸面就少得多,打水氣泡也很少。
因此我猜測可能因此溶氧量不足,
不想降低水位,所以我弄來一個水妖精,每天開個2小時~8小時。
4. 可能是水質偏酸性:
紅雙劍屬於弱鹼性魚,若台北的水原本就偏酸,
而中性的玫瑰石底砂無法像珊瑚砂那樣將水質調整成弱鹼,
不想換底砂(玫瑰石很漂亮...)
所以,計畫去買水質調整劑來作修正。
5. 其他:增加培菌機制。
在水妖精裡添加一些貝殼砂;在外掛多加一小包陶瓷環(原就有一小包);
在外掛下方套上黑色生化棉。
請教板上前輩:
還有其他可能導致縮鰭的因素嗎?
在這樣做了一週之後,我可以再進紅雙劍了嗎?
※ 引述《WangWoody (老大不小朋友的新開始)》之銘言:
: 3/3早上忽然發現缸內花鼠*1、紅白劍小魚*1 歸天
: 缸內兩隻紅雙劍則有縮鰭現象
: 雖然偶爾還是正常出來游動一會,但多數時候都躲在小榕邊不太動
: 其中一隻身體扁瘦得不太像正常的樣子
: 想請問紅雙劍縮鰭該怎麼處理?這是紅雙劍的夾尾現象嗎?
: 3/1剛換過水,想起來那次的新水曝氣時間好像只有近24hr而已
: 但因為怕曝氣不足我都會加水穩跟鹽巴...
