Will regular harlequin rasbora school with gold harlequin rasbora?

i have 6 normal harlequin rasbora and i notice that they do not school much but they do in very loose schools so i figured i could fix that by adding more to the population. i'm wondering if golden harlequins will school with my regular? also in my tank (25 gallons) i have 1x oto cat, 3x neon tetra, 2x bumblebee goby, 1x guppy and 1x weather loach. i am thinking of only adding rasbora and as the others die, naturally, of course, i'll just keep adding rasbora until my tank is stocked. do you think this is a good idea? also when every fish is gone except the loach( because it can live more than 10 years) could i add another to keep the original company? thanks in advance :)
