Well for one your fish should not have been together in that tank if you had no intentions of spawning them. If you did, you should not have left them alone un-attended while you were at school, this kind of project is a major undertakeing and requires your complete attention. But all that aside.
You should probably have left the eggs on the bottom of the tank, with moderate airation and decent water quality they would have been just fine, the male does not have to hatch them in his nest for them to survive. I recommend you re-introduce the eggs you have removed back into the spawn tank before they hatch, as afterwards they will certainly die either way. I wish you good luck.
*Note*
If your male is not careing for the eggs at all i recommend removeing him soon as he will likely eat the eggs and new born fry. If the female is careing for the eggs she should stay with them untill they begin to hatch.
