What do I feed the newly born fries?
As guppy is live bearer, it is quite easy to raise their fries. Some may take finely crushed flake foods from the start, and only require frequent water changes to keep up with their growth.
Personally I prefer to feed them with hatched baby brine shrimp. You may also use live daphnia. These live food are most ideal for fries in their first 1 month.
Try not to overfeed in each feeding session as uneaten food may cause the water to foul up. Feed what the fries can finish up in not more than 5 minutes.
