Nano schooling fish suggestions

[Khuligirl93]

I'm trying to decide on a small schooling fish for my planted 20 long. I'd prefer a species that stays under 1.5" so I can have a large school of 15+, and my tank has an open top so it can't be anything that is prone to jumping.
What I've considered:
Chili rasboras
CPDs
Blue Eyed Gertrude/Spotted Rainbows
Clown Killies
(I really like the idea of something a little more unusual, and I have seen all these at a LFS surprisingly)

I think Scarlet Badis are beautiful, but I'd prefer something that eats flake and frozen foods.
Suggestions and experiences with any cool nano fish welcome!

I have CPDs and they are small,colorful, active and show no sign of being jumpers.
I wish I had more info chili and other micro rasboras. I like them.
If Gertrudes are anything like Furcata forktail rainbows, I find them to be sensitive to excessive CO2. I killed off a school last year after making a bad adjustment to the bubble count. They are IMO on the larger side for nano fish. They have this shimmy when they swim reminiscent of a molly in distress, if that makes any sense.
I have no experience with clown killies.
Ember tetras are another nano fish to check out.
You could continue the nano theme with a school of pygmy cories.

Gertrude rainbows stay smaller than furcata rainbows, but I will do a little research on their CO2 sensitivity. Thanks for the input
I have had ember tetras before, but was hoping for something a little more exotic

Got 8 CPDs http://i349.photobucket.com/albums/q381/bnz0429/8B8FBB4A-8E5D-4CCE-A57D-E89BC698BE92_zps60lig6jp.jpg
I'll get 10 or so more once my tank is more established

And also 3 sparkling gouramis (they relentlessly hunt my shrimp all day long) http://i349.photobucket.com/albums/q381/bnz0429/B0BBA32F-3752-4053-95E3-30558BFA3041_zpspzz3k7ty.jpg

Rainbows and Killifish are both jumpers.

CPDs are awesome !
Sparkling Gouramis are micro predators and will HUNT Shrimp [emoji53]
