How Many days dose the baby fish need to be separtes from it mother?

Baby fish, or fry, typically need to be separated from their mother once they are free-swimming and able to feed on their own, which usually occurs within a few days to a couple of weeks after hatching, depending on the species. For many species, this can be around 3 to 7 days. However, some species may require longer periods of parental care before they are fully independent. It's important to monitor their development and ensure they are ready for separation to increase their chances of survival.
