Congrats on your success! The fry are rather fragile in the 1st 2 weeks of their life, I'd recommend doing minimal water changes, or even no water changes (if your filtration is good) during this time period.
Aside from this, the mum should take care of her brood for a month or more. During this period, just ensure optimum water conditions and sufficient food, especially since you've removed all other fish from the tank.
