Adult guppies can survive without food for up to 2 weeks. Guppy fry can survive for about 3 days without food. However, there are few things to consider before leaving your tank for such a long time.
Guppies can live without food for weeks, so long as the water conditions are right. If you have guppy fry, you need to feed them at least once a day. So it’s not a good idea to leave fry unattended.

Before You Leave
- A few days before leaving do filter maintenance.
- One day before you leave, do a water change (50-70%).
- Put aquarium lights on a timer (your guppies need to sleep and won’t do so with constant light)
- Get rid of decaying plant matter or dying fish.
Things You’ll Need
- API Quick Start – Use this to add nitrifying bacteria to help keep the colony stable after you perform the huge water change.
- Timer for lights – if you can’t buy a timer then leave the lights off completely and allow for natural light to reach the tank. Your plants need light.
- Automatic Feeder – For guppy fry, automatic feeders are a great option to feed them while you are away.
