Bad Luck with Zebra danio Breeding

[John Bignell]

I set up two 5g tanks with males and females separated, after five 
days I moved the 5 males into the 4 female tank.. I did this at night 
time and covered the tank till I got up the next day. But I didn't 
notice any eggs or mating, after five hours I moved the males out 
and left my biggest female ( about 3-5cm) in the breeding tank. 
how long should I wait till I try again and should I only place one 
male back in with her or 3 males........  

Any suggestion will be of great help......the easiest egg layer is
give me so many problems :)

thanks for your time

John
