If the eggs are on an object that is removable can take them out now. Just make sure there is good flow over the eggs so they don't go bad, you have to replace mom and dad in fanning the eggs. Could wait for three daysish for them to hatch then just suck them out with a syphon hose.
I would leave the first couple batches with them. Will lose a lot but they will learn how to care for them. Then you can just pull them as swimmers. Will help the mom out a lot. As soon as the fry are gone dad will want to breed again. Mom needs some time to make more eggs. Tending wigglers/eggs giver her time to do this.
