黑殼蝦會慢慢死光 - 魚

小弟養的魚缸是4尺2,因為使用上層過濾所以沒有打氣,
之前因為有渦蟲擔心會攻擊蝦子所以使用捕捉器捕捉,數量也已大量減少,
從每次可以捕獲上百隻到現在每次只能捕捉不到五隻所以就沒再捉了.
小弟每次都買一兩左右,基本上放入水中會因不適應水質死掉的很少,
只有前三四天每天兩三隻而已,但蝦子就是會一直不見,大約一個月後就剩不多.
也曾看過很多小小蝦,但是似乎很少長大的,
是換殼被魚攻擊死掉還是溶氧不足會慢慢死掉?
但大和藻蝦又可以活很久,所以一直好奇黑殼蝦是溶氧不足還是被吃掉.
小弟混養的魚有斑馬魚約20-30隻,紅蓮燈約30隻,三角燈約10-20隻,孔雀約10隻,
大和藻蝦5隻以下,魚缸容量約有將近300公升.
另外一提之前有買大一點的黃金米蝦,體型約4公分,但也是會慢慢消失,
是米蝦需要比較高的溶氧量嗎?還是換殼時會被魚攻擊?但大和藻蝦又不會?
這問題困擾小弟很久了,希望有大大能夠指導,感激不盡.
