In the thread that this is in reference to, I said it CAN. I did not say this was a 100% positive method of keeping, but it can work in many cases. I was only pointing out the completely incorrect statement that overcrowding CAUSES aggression. Aggression is not caused by anything. It is not a disease, it is a habit. In the cases that it does work, adding more fish simply spreads the focus of the aggression among multiple others.
For the reasons above, I did not vote, as there is no 100% anything.
