Bronze Cory Eggs

[mreyeball]

i have 2 bronze corys, no idea what sex they are but at least one is female as i found eggs stuck to the glass of my tank yesterday.
my question is do corys lay/spawn eggs if they are not fertilized?
thanks

I think they can... what size are your cories? females tend to be chunky & bigger,whereas males tend to be slender & more streamline especially when seen from above
