OK well here's what I can make out of your situation. You can't really call danios "pregnant" because pregnancy is when an embryo is inside the mother. Since danios are external fertilizers, they need to fertilize their eggs outside of their bodies. If your females are large, then yes, they probably do have eggs. If you want to save the eggs and raise the fry, you need to create a simple breeding tank. If you'd like to do that, let me know and I'll give you a set up. Your fish could possibly be breeding already. But you will never see the eggs since they're small and are likely to be eaten before you have the chance to look.
