Yes, what Ted says makes sence to me, as most eggs do not last for days when they are not fertlized. The only disadvantage with labyrinth fish is that they have whitish eggs and you can not tell they were not fertilized becouse they do not get white within couple hours. Only some killifish eggs last very long even when not fertilized as they have the super thick chorions, but again they turn from clear to white and even before that you can clearly see there is no perivitelline space in there so you can remove them before any kind of fungus becomes an issue. Thats what seems to me like a problem when you remove the eggs and hatch them without the male as I dont know how to recognize the dead eggs before they are covered by fungus. I have to try on my own as soon as I have enough offspring of my first paros.
