awesome! the only fish babies i have had are platties and swordtails. they are livebearers and therefore easier, but yeah you do have to watch for the babies and put them into a breeder box or separate tank before the other fish eat them up. yum! i have 2 babies right now that are about to move over into the big tank now that they have grown up. i've never had oscars, but i hope you get some babies!
