Well the female has to be gravid then I prep the tank I will be using with fresh tap water then I place the green spawning mops that I make in the tank some what towards early evening I place the female in the tank usually and preferably on a full moon night once she settles I introduce the males and if it's a little warm I would probably place a couple of bags of ice just to cool the water down a few degrees I also place a light over the tank and sit back and watch. The original trio I started this thread with started doing their dance around 9pm or so but I think what happened there was I had added a younger male and he somehow messed things up that night. Now I'll go back to the green mops; about four days after the eggs hatch they start looking for food and even thou I supplement with green water they fry start gravitating towards the mops and there they can start munching on the green material growing on the mops it's kinda like being ready for them the fry ahead of time I believe this helps them get on powder food sooner.
