eggs laid in middle of night

[freemanm]

Ever since the daylight savings time change this week, our fish have 
been laying their eggs when the lights go off or in the middle of the 
night.  Does this happen in everyone's labs when the time changes?  Is 
there a good  way to convince the fish to lay in the AM, with the lights.  

Thank you,
