Well, congrats! It may be your "big girl" was just happy to have another angel. Hopefully your new 1 is a male & figures out what to do since "he's" a little small & probably inexperienced. We had 2 females that laid eggs regularly, taking turns then eating the eggs. We introduced a young male & flirt as he might, they were set in their ways. If you really want to raise any fry you'll need another tank, it's not a community tank process. But if you don't care all that much (raising babies can be a PITA), just enjoy their behavior & nice fresh food for everyone. They can be aggressive to tankmates so be aware & maybe add some décor, plants etc, & hope for a happy tank. None of your fish probably inhabit the same area as the angels but everyone likes eggs!
