Looking at the pictures I don't see any male that really looks in a sexually active mode right now. Therefore, I doubt that you'd get any breeding activity that quick. Mind you, once they're all settled and well fed such a move could trigger them. My first fry came 2 weeks after putting my first fish into the newly set up 65 River-Tank. Up until then they had lived a few weeks in a 10 gallon holding tank after bringing them over from England.
The change into a better environment got them going.
