Oh gosh! What happened to my Red Cherry shrimp? Ate by Amano shrimp............ =.=I was afraid the water quality still unstable, cause the shrimp died, tested the pH 6.2 and KH 2.0 by this morning , after calculated the CO2 level is 37.86ppm, it should not be the cause of killing the shrimp. Is a big question mark to me now.
