So the last two times my Jd layed eggs the eggs have developed a fungus and do not hatch. The male is in the tank with her, and they have had many batches before. Anyone have an idea on whats going on. I guessedd that he didnt fert them the first time but why would he fert them, he guards them with her like he did.. Could it be something in my water and if you think hes not fert the eggs why would he be if they have already had many batches..
