we all know that Petrochromis are impredictible fish, but very often when they are kept alone, they can become very aggressive towards other fish also of very different species.
It seems like they need however to download their aggressiveness, or they get bored and need a way to spend their time.
Conversely, when there are other (better many!) specimens of the thier species in the tank, they do not care at all about the other species!
