Fish eggs typically hatch within a few days to a week, depending on species and temperature.
Start Immediately
You should begin feeding fry as soon as they hatch. They rely on a yolk sac at first, but once it is absorbed, they need external food to avoid starvation.
First Foods
Offer infusoria, rotifers, or commercial fry food in small, frequent portions. Monitor water quality closely with regular changes and filtration.
Research the specific needs of your species for the best results.
