Oh, no wonder it looked so nice! If you're really afraid of them eating the eggs, I suggest you stop disturbing them with your picture taking and such. Disturbing them will only make them feel threatened and will eat their eggs if they feel the area is unsafe to raise fry. You can move them if you like, but I think you should leave them just because I'm a fan of allowing the fry to be watched over for 3 days by at least the mom.
EDIT: I think the eggs are infertile.. But wait a few days.
