Harlequin Rasbora Breeding

[dewiro]

I've heard these are near impossible to breed but when I bought them from my LFS I came home to realize my 2 females are prego. I bought a breeder and stuck a male in there and i put a few small plants in there for them. Last night the female kept turning upside down and then the male came up next to her, wrapped his tail around her and they started the dance. Now... i'm completely new to the fish world and i'm desperate to save the fry. I havent been able to find anything online about it that makes it obvious and clear as what to do. How long will they continue to dance and when do I need to remove them from the breeder? There are 2 prego females and 1 male, currently in a 40G tank but i'm about to move them into an empty 10G tank by themselves
