I was watchin my fish today while handing out candy and they all seem to be geting a bit aggressive. Not sure if it has to do with the fact that I just started feeding them other foods, in general, chicken. The plecos are fightin, the 2 big osacrs are pickin on the albinos, the one bala is bettin the heck out of the other, blah blah blah. It's an all out war in there. Is this a survival of the fittest contest and should I be worried? The arowana is the only one clear of it all.
