Hi,
I had had two Congochromis females, one of them died recently and the other one now behaves similar to the one that died. She hides most of the time and she's breathing really rapidly. I tested for nitrite but it is not elevated (I had rapidly breathing fish in another tank and then nitrite was high and a water change cured it). I added some air flow with an airpump but the problem seems to persist.
The other fish look fine (two male Congochromis and a pair of Epiplatys olbrechtsi). I recently treated with a dewormer, they are up for the second treatment in a couple of days.
What could be the cause of this behavior? One of the males is quite dominant, could the rapid breathing be a sign of stress?
