I was wondering if you guys have no problems with german blue ram in your tanks.
I`m trying to get a stable level of co2 in my tank so I adjust a bubble rate to achieve that goal and noticed one thing. When I add more co2 my rams are in stress but other fish like rosy barbs are just fine. I`m wondering if co2 issue in our tanks has someting to do with the fish we keep in. It`s possible that when we try to adjust co2 levels just looking at fish behavior we still can not get to levels that will be required.

Any idea?
