[Lupin]

ok ! so i think i decided. . maybe. . would Corydoras hastatus work with Boraras brigittae in a 10 gallon ? and if so, how many of each would work ?

Yes, I don't see how the cories can attack or bother their fellow tankmates. Being small, you can have 10 cories if your wallet permits. Wiht Boraras species, 20 can actually fit. Still the same as the case of 100 neons in a 55 gallons tank. I doubt Boraras ever would contribute too much wastes.
