I know what you mean, I've had fish that didn't act the way they were supposed to...like one scaredy cat male betta who was afraid of everything
I've also had peaceful cichlids who were supposed to be mean and mean tetras which were supposed to be peaceful. IMO fish have individual personalities, what we read about is just what can generally be expected...not always the case!
