I guess the biggest question is...do you really want more Oscars?
When you buy fish of any species, and they breed, that should be considered as an indicator that they are being kept reasonably well, in good water with decent food and space. Congrats are in order. But it shouldn't be automatically assumed that every little blob of life that they deposit on a rock or flowerpot must survive. It doesn't happen that way in nature; that's why there are so many of them in the first place. A tiny fraction of a percent will survive to maturity; the rest vanish, mostly into the mouths of other critters, some of which might be their parents.
IMHO, you should just enjoy the spectacle of a pair of very cool cichlids laying their eggs, messing up their first few attempts at being parents, and likely eventually succeeding and caring for a brood of growing young. Then, before you get too attached to the little ones and start naming them and setting up college funds for them...get rid of 'em! You can't keep all of them, no matter how much you think you want to; they'll grow like wildfire, they'll require many tanks, many gallons of water, much work and space and money. It will stop being fun really quickly. Try to keep them all, and all will suffer, including you.
Just take care of your adult Oscars...let them take care of their little ones...and when/if you eventually find yourself with a school of one-inchers, trade 'em in at the LFS, give them away, sell them privately, whatever.
Don't continue on down the road you're starting on, the one where you use phrases like "Poor little guys didn't stand a chance". That way lies madness!
