Fluval Flex 32.5 stocking ideas

[Canuck AquaTropix]

I have a Fluval Flex 32.5 planted tank.  My wife and son are challenging me to stock it with the MOST colourful freshwater fish possible lol.  We want it to be peaceful so want to stick with Tetras, Rasboras and peaceful Barb's.  No livebearers and no Glo Fish please.  What species would you suggest for bottom dwellers, mid level and upper level inhabitants?  I'm trying to think outside the box and steer away from the usual suspects but it's not easy.  Looking forward to hearing your suggestions.

My more colorful fish are German blue rams, psuedomugil luminatas, and honey gourami. Photos of rams and honeys are mine but my luminatas are to fast so took a web photo 

For bottom dweller Adolfo corydora are so awesome to see. I don’t have them but my LFS always has them. (Web photo)

I don't think anyone has had a "more fun tank" thank Filipe's ram tank. I would definitely add in some shrimp and focus on something that works with said shrimp. Especially caridina.... you're talking some pretty bonkers colors.

There are so many beautiful rare Killie fish.

Maybe not unusual but a pair of pearl gouramis would be nice.
