As long as you keep the water warm and mimic june's weather, you should get a spawn once they are nice and comfy. But I had mine for a year until they started to spawn. They did every 2-3 months for 4 times until I had a crack at the bottom of the tank and all the water leaked out, leaving two lovley fish dead and dried up. 
I had no interest in any more greenies, as these 2 were enough so I left the fry in there. They'd get to about an inch till the parents decided to spawn again and would eat the remainders.
