Clown fish eggs

[foxfishfan]

I too have 2 clowns that lay their eggs in different places about every 3 weeks and watch them aerate the eggs by fanning them with their fins and blowing on them. I even tried to place a net around the area big enough for the parents and no one else but sure enough, about 5 days later the rock is bare as if they were never there. I'm not sure if they get sucked up by current into the powerheads or eaten by the parents and their tankmates. If you do attempt and suceed, let me know what to do.
