nice pics.
i keep a dish of mealworms in my leo enclosures at all times and then feed crickets every 3-4 days.
leos aren't usually aggressive unless they have never been handled at all--might that be the case with these?
you should separate the male from the females (with both the leos and the afts) so they don't breed and you wind up with lots of babies. looking at the photo of the albino leo i can see that she doesn't have enough fat reserves to be in breeding condition anyhow...
