The danio certainly looks gravid (full of eggs) but unless you have a breeding tank set up you are unlikely to see any offspring. They lay eggs and they usually get eaten by the parents and other fish before you know it they even spawned.
Rule of thumb with livebearers is that if they are in mixed sex groups, the females are always pregnant. Unless you have enough room for all the fry, and there will be thousands, let nature take it's course and leave them in the tank, that way the majority will be eaten and you won't be overrun.
