Ah, found your edge thread! I like your plant selections, very cool with the light substrate.
How's your water? If you're on the softer side you might consider ember tetras, really pretty tiny tetras. I love them but am not willing to do the RO water to make them work in my tank. I like sparkling gouramis as well, but I'm not sure if the small airspace would be an issue with them like it has been with for some people and bettas in this tank.
I'm in debate about dwarf cories in my edge too, I have two types in my 29g and I can't decide if I want to try moving some into the edge or not. I like my habrosus best of the two species I have.
If you want oddball type fish, what about scarlet badis? I hear they're pretty fun little fish.
Following your thread now too.
