Im sorry for your surprise.
Can't wait for pics when its set-up!
Have you considered Celestial Pearl danios (Galaxy Rasbora/ Danio margaritatus)? They are a great nano fish, Only get around an inch. The only thing I see wrong with these is that they will eat little baby shrimplets.
Clown Killifish (Epiplatys annulatus) only get 1.5 inches long and a beautiful. I know my killi pair are very explorative, so dont be expecting it to be shy
Scarlet Badis (Dario dario) are very small, barely reaching an inch. The male displays great color, but they are pretty shy.
Chili Rasbora (Mosquito Rasbora/ Boraras brigittae) can reach around 1 - 1.5 inches. They school decently and are a vibrant red.
Endlers Livebearers (Poecilia wingei) are beautiful and only get 1 - 1.5 inches. If you plan on getting both male and female, make sure to use the 1 male per 2 females ratio.
Sparkling gourami (Trichopsis pumila) also stay pretty small, around 1.5 inches. They also have very pretty blue eyes. Not seen in many gouramis.
Hope you liked the list! Really all I could think of...
