Caring for fry is hard popcorn, but you should be able to get a breeder box for under $10 at a pet store or someplace like walmart. Most of the fry should be able to grow big enough in the breeder box to keep from being eaten. Otherwise, if you have enough places for them to hide in the tank you could still end up with a few (maybe 2 or 3) that survive by running and hiding until they are to big to be eaten. You best bet to save the fry though is to remove them or the other fish to another tank.
