If buying from pet stores, I would defiantly QT.
But you can also buy females from a breeder who have been raised in the same tank together(siblings usually, but some people mix same-age spawns).
If buying from the pet store, instead of using those cups you can buy food storage containers in sets of 3-10 that hold two or three times as much water, generally for less than $5(I just got a set of 10 for like $3).
Accumulate like you would any other time, float them/add a little water at a time so they get used to it. I would add all the girls at once so that no one has territories yet.
Some girls are just /too/ aggressive, so be prepared for that(be it setting up a new tank or exchanging her for a new girl).
