Re: [APD] Re: Can one just give up? - Similar story

This sounds to me CO2 poisoning (is this the right discription?), some fish
are more senstive to CO2 than others. I usually spend at least 2 hours to
slowly adjust the fish to my tank's 30 ppm CO2 level, I use an pH probe to
monitor the process. Since I found that some torlerate CO2 very well while
some (or even some individual) don't torlerate at all.
