Thought this was interesting.
a few days ago I was at the National Aquarium in Baltimore. I was fairly impressed by their Amazon biotope tank - it was quite large and had a good mix of relatively compatible fish in it. Unfortunately, no discus - would have been nice, but I think they don't want to spend the money for fish that might be easily eaten (check out the "king" of the tank at the end)......
... and instead they have what look to be common Angelfish. One large one swam way off by himself in the "open water". Another trio hung out with each other in open water. But there was a big school that hung out near a fake tree stump - much like in the wild, I think.
Here's an example from the wild:
