That's unfortunate about the Congo's. How many did you have? I have 7 and they are a joy to watch. They play tag in the morning, but no one is ever singled out. It almost looks like a relay race. Sometimes they will plow into the Bloodfin Tetras and scare them making them school up and swim across the tank in a tight school. I absolutely love mine.
That being said I'd at least double the size of those schools. I know neons and glow light tetras aren't the best schooling fish, but 20-25 of each along with 20-25 Rummynose or my favorite Bloodfins would really look cool.
I also like the scape of your tank. Very jungle looking but it still has a lot of open area for them to group in.
Perhaps that was an issue with the Congos. My tank has several very large pieces of driftwood that extend out of the water. There are huge line of sight breaks.
