How long before clowns will Breed?

[russp]

i have had my false percs for nearly 3 years & all of a sudden 2 weeks ago they laid eggs & the 2nd batch is probably going to hatch tonight . I am going to find some phyto & rotifers & set up a hatch tank soon & try my luck . I have no idea why they started now , I moved a year ago & have been fighting high nitrates until recently . they are laying the eggs on the silicone in there back corner of the tank , i assume they will start when they are ready.
