Hey there. In all honesty 10g is fairly small. I'd be looking at blackwater nano species like chili rasboras, ember tetras, pencils, dwarf/croaking gouramis, bettas etc. Floating pads will help save a lot of space. What are you looking at for lighting? Also, what water volume are you looking at? Alot of this will determine stocking options.
