Nah, most of my tincs are in groups, and they do just fine. The 1.2 group is probably about as productive as 1.1 would be, but I rarely see any signs of aggression. I tend to plant my tanks pretty densely and the average viv size I use is right around 45 gallons, so the additional room and visual barriers probably help.
