I noticed my Jags acting weird Tuesday afternoon, laying down on the bottom of the tank and not moving, not defending their babies. So I tested my water and my high ph range came back around 8.6, everything else was perfect my regular ph is 6.8. So I did my regular Wednesday water change and put some acid buffer in and the high ph is back to 7.4 and the regular ph is still 7.4 but my Jags are still laying down and sometimes they get up and scratch and they open and shut their mouths real fast like they are choking or something. I have tested my water everyday since and its still fine. My midas and neetroplus that are in there are acting fine so I cant figure out whats going on. Any help is appreciated.
