Congrats Fanatic!
From what I've noticed is that @ two-thirds of the time, both parents take turns guarding the eggs, and there is usually a little bit of aggressive behavior when one parent 'tells' the other what they should be doing - to get back to guarding the eggs and quit wandering off or otherwise letting their guard down. Or, one parent decides it is his or her turn to guard the eggs and chases the other off.
As for the other one third of the time, the majority of that time it is the male who dominates over guarding the eggs. I've seen the females do what you described as well, it's just not as common.
The fertilized eggs will hatch more quickly in warmer water - 84 - 86 degrees than say, 80 84 degrees. They generally take 48 to 72 hours to hatch. After the first 24 - 36 hours, you'll know which eggs are not fertilized as they will be much lighter - a light cream to almost white color, and the tannish-grey eggs that are fertilized will start to more clearly show little tiny black eyeballs (you have to look
really closely to see this).
Keep a sharp eye out for any light/white fungus that may grow on the non-fertilized eggs as the fungus will very quickly spread to the 'good' eggs and kill them. The reason the parent(s) fan their fins over the eggs nearly constantly is they are attempting to keep any fungus from forming on the eggs.
I don't know what size tank your rams are in, but if it is a relatively small tank, you might want to squirt some peroxide into the water to help kill any fungas that may grow. It won't hurt the fish at all.
My advice? If you want to have the best outcome for the eggs/fry, and if you have a tank or tank-like 'thing' you can place the eggs in and hatch them yourself, your chances of having survivors are much greater than leaving them with the parents. I wish it weren't so, but the vast majority of the time, the parents or other fish will eat either the eggs or the fry.
Watching it all is pretty interesting stuff, ay?
Keep us posted!
