Also, the first batch of eggs from a pair usually doesn't yield a lot of fry. Don't be disappointed if they don't hatch this time, in time they should get the hang of it. Also, if you really want to breed them, I would remove the catfish and any other fish that will eat the eggs.
Is your dad willing to hatch brine shrimp or anything to feed them?
