There is the Blue Neon Rasbora (Sundadanio axelrodi) and possibly the jelly bean tetra, but both are soft water species (Ph 6.0 and under). I have done a similar tank with Bororas and CBS, but the evaporation rate is crazy. In a 6 gallon open top, I was going through 3-4 gallons a week not counting water changes. I was able to drop the Ph in mine well below a 6 with just Distilled water only and Brightwell soil. I would be wary of using any C02 in a tank like that though, as it can belly it out in no time at all.
If it were up to me, I would likely go with tap water and perhaps eco complete or just a nice looking sand substrate. I would rely on Excel for carbon and supplement with root tabs. Go with some Anubias nana petite, Flame and christmas moss, maybe some willow even. Some crypts in the rear of the tank as a backdrop. All low maintanance and require low light. Pack the tank well to settle it all in until it finishes cycling to avoid any algal bloom. For filtration maybe run a zoo med canister with some extra long hoses from Home Depot, just add a pre filter sponge in black and it should be inconspicuous. I'd go with those Blue velvet (fairy) neocaradina shrimp. Speedie on the plated tank usually has them and a few boxers have them, just somewhat new and not sure if any are selling offspring yet. Adding a small desk lamp that accentuates the tank could go far in increasing the light available for the plants. I'd certainly add some crpts to that upper area as they do well growing emmersed and would look great flowering.
