Guppies are popular fish that can be found in most pet stores. They’re small, colorful, and have a lot of personalities. And they’re also pretty easy to care for, as long as you know how to look after them properly! One thing that many new guppy owners wonder is: how long can guppies go without food?

How Long Can Guppies Go Without Food?

If you’re only going out for the day, then it isn’t really necessary to worry about food at all. Your guppies should be fine until you return! 

Adult guppies may go for up to two weeks without eating, while guppy fry can go for up to two days. Guppies, on the other hand, will eat algae and other small organisms in your tank, so you won’t need to feed them if your tank is already established.

It’s reassuring to know that your guppies can comfortably survive a fasting spell. At some point in their lives, every fishkeeper has grappled with arranging fish feeding.

In general, it’s best to err on the side of caution when it comes to feeding your guppies. If you follow a regular feeding schedule and make sure that they always have an ample supply of food, then there’s no reason for them to get hungry in the first place.

Guppies can go for weeks without eating if the water conditions are appropriate. You should feed your guppy fry at least once a day if you have them. As a result, leaving fry unattended is not a good idea.

Ways To Ensure Your Fry Survives While You Are Away

  • Prior To Leaving
  • Perform filter maintenance a few days before departing.
  • Replace the water one day before you depart (50-70 percent )
  • Set the aquarium lights to a timer (your guppies need to sleep, and they won’t be able to do so if the light is on all the time)
  • Get rid of any dead or decaying plants or fish.

What You Will Require

The best way to keep your tank stable after performing a water change is by adding nitrifying bacteria. This will help reduce the number of harmful chemicals inverts produce and make it easier on you, as well.

If you can’t afford a timer, turn off all of the lights and let natural light in. Light is required for your plants.

This automatic fish feeder is perfect for those who want to keep their tanks clean. Simply place it in the tank, turn it on and watch as hungry guppies queue up.

But what if you don’t have an auto feeder? Well, then it’s time to get creative! The good news is that many people find these instructions work well with any type of fish. It all starts by making sure your aquarium water quality meets or exceeds the standards set out.

How To Get Your Aquarium Ready For A Vacation

Guppies are surprisingly tough. A healthy guppy can go for one week and probably two or more without any problems! Spending some time preparing your aquarium before you leave also helps them survive, but be careful not to overdo it because that might kill the fish

Aquarion is hardy too – they’ve been known never to die even when their tanks break apart during an earthquake.

Important Points to Consider

  • Guppy fry can survive for significantly longer in some aquariums when microfauna and algae are present.
  • Feed the fry once a day using the automatic timer.

How Often Do Guppies Need To Be Fed?

Guppy should be fed once or twice a day, depending on the type of food you are feeding. It is important to make sure they have plenty of food, but you should also watch for overfeeding (which can lead to health problems). Always remove any uneaten food from the tank, as it will rot and pollute the water.

What Do Guppies Consume?

Guppies are omnivores, meaning they will eat both plants and animals. They feed small insects, crabs, and other small organisms in the wild. They can be fed flakes, pellets, live food, and frozen food in captivity. To ensure that your guppies receive all of the nutrients they require, you should feed them a diversified diet.

What Do Guppy Babies Eat?

Newly-hatched guppy babies will feed on their yolk sacs for several days, so you don’t need to worry about feeding them right away. Once they are free-swimming and eating on their own, you can start feeding them baby brine shrimp or other small live food. As they grow, you can gradually start giving them larger food items.


How long can guppies go without food? It is a good idea to have some food available just in case they get hungry while you’re gone. That way, you can rest assured knowing that your fish are being taken care of and won’t go without food for too long.

But if for some reason your fish do end up going without food for longer than a few days, it’s important to keep an eye on their health. Signs that they are starting to experience health problems include lethargy, loss of appetite, and weight loss.

If you notice any of these signs in your fish, it’s important to take action right away. The sooner you can get them back on a regular feeding schedule, the better their chances will be of making a full recovery.
