When guppies are born, they obtain nutrients by sucking nutrients from their yolk sacs. You don't need to feed them for the first few days after hatching because they haven't started eating yet. However, after about 3-4 days, you can start providing appropriate food to your baby guppies.
You can use small pellet feed designed specifically for juvenile fish or a specially prepared liquid food. These foods should be easily digestible and provide them with adequate nutrients. Please note that baby guppies have small mouths, so food particles should be very small, and overfeeding should be avoided to prevent water quality problems.
In general, it is recommended that you start observing and feeding your baby guppies within a few days of their birth to ensure they are getting adequate nutrition during the early stages of their growth.
