why don't my cory eggs hatch?
I have collected 2 lots of eggs that my peppered corys laid. A lot of them turned brown so i know they were fertilised. I removed the white ones. The 1st lot took 5 days to produce some 'wigglers' but after a couple more days these died. I now have eggs laid 5 days ago but nothing happening except that a lot have turned white.
What can i do? I really want some babies and mom and dad are very obliging all i have to do is put them in the nursery tank at a temp a couple of degrees lower than the commumity tank and the next day i have eggs which i then harvest and put in a breeding box.
