Dude,
I have/had a few gouramis. They are indeed top to middle feeders, occassionally dwelling to the bottom. Everyday I do a John Arthur, that is feed flake when I turn the lights on, and black worms, or bloodworms before I turn off the lights.
Their body structure emulates a fish that doesn't live in very fast moving waters because they are bigger, and slightly rounder. I believe that fast moving water fish are very torpedo like.
I recommend using this website if you have some basic questions about the fish.

After reading about the flame dwarf, they before heavily vegetated waters which means slower movement, but they can tolerate it, as mine did. Check out my pic, you will see him.
