I have noticed an increase in activity but less aggression in the past when I have added black water extract. I haven't studied it systematically enough to say for sure the extract is what makes the difference, but assuming it is I don't know if the darkening of the water makes them feel more comfortable or if it would be due to the peat or other actual ingredients. The main times I notice increased aggression is simply when they are hungry and need to be fed. I don't know enough about ph to comment on what differences that might make.
