eggs laid in middle of night

[Carrie Jones]

We have not seen that here but if you use crossing cages you could try 
and put in dividers so the male(s) and female(s) are kept separated 
overnight.  We use a piece of acrylic cut to size.  Then in the morning 
when the lights come on pull these dividers and the fish should lay as 
usual.  Maybe trying this a couple of nights will get them back on 
schedule.  Good luck! Carrie
