I found the tendancy of many Geophagus to live in heavier current areas than usually thought of, very interesting.
And that using higher pumpage on their tanks, might be a major factor in maintaining good health.

In my opinion maybe the best recent development for the hobby is how technology has created a cottage industry for wild underwater videos where someone who can't travel there gets to see natural settings, behavior, species found together, varied locations and habitats, etc.
Not in this video, but another interesting thing is when there are rocky spots in rivers or areas we don't think of as rocky and some familiar species we might not expect in rocky habitat. "Biotope" can vary a lot in the same river, sometimes for the same species.
...In reality, an "Amazon (region) tank" can be a lot of different things.
