If your tank is large enough to accommodate both breeding pairs without conflict; if their territories don't overlap; if they seem to respect and stay out of each other's territories; I say, "If it ain't broke, don't fix it."
If you plan to keep any of the fry, however, you'll need to make arrangements for them quickly. Maybe a couple of fry nets until you get one of your smaller tanks freed up to use as a fry tank.
