If there’s nothing we can do and we have to be gone because that a spell, just just how long can fish walk without food?

How Long have the right to Fish walk Without Food?

Most healthy aquarium fish deserve to go 3 days come a week without eating. However, it normally isn’t recommended to go an ext a day or two without feeding unless fully necessary.

This number may vary based upon a few factors:

How active Are your Fish?

How long your fish deserve to go without food depends greatly on the line of her fish. Smaller sized fish often tend to be very active, which way they need an ext food 보다 slower, bigger fish.

Small, schooling predators like Tetras and also Rasboras tend to it is in continually active. The method they dart about, nipping at one another and also exploring their residence is part of their charm!

In nature, this fish would be constantly “grazing” as plankton, insect larvae, and also other food sporadically drifts by. In aquariums they acquire a huge feeding every at once, which filling them up for a couple of hours. Still, you’ll require to provide food 2 or even 3 times every day for these guys!

The warmer the environment, the much faster the metabolism of your fish. Countless tropicals, choose Danios and White Cloud Minnows, can additionally thrive in room temperature or cooler water.

In cooler tanks, we should be providing them either less food every feeding or providing food less often (1-2 times every day). Any more and you’ll run right into either fat fish or uneaten food going to waste.

Are her fish herbivores or carnivores? because plants tend to be abundant yet low in nutrition, herbivores often tend to graze continually. Castle need big amounts the this lower energy food to preserve their weight. Carnivores, top top the various other hand, can eat a single meal and digest because that a longer duration without eating.

How big Are her Fish?

Body fixed is simply as essential as metabolism and for plenty of fish the 2 are carefully related. Typically speaking, bigger fish have slower metabolisms than smaller sized ones. However, bigger fish additionally need more food to keep their body load than smaller ones, so it’s a trade-off.

As a rough dominion of thumb, bigger (adult) fish deserve to go longer in between meals than smaller ones. In fact, adult fish with slower metabolisms prefer Goldfish yes, really only have to be fed a single time per day.

Adult Goldfish are several of the easiest fish to overfeed as they will certainly eat constantly nevertheless of how much they were fed earlier. Not only does their metabolism slow-moving down as they age yet they are also cold water fish.

While girlfriend shouldn’t shot to check this, most fish have the right to go anywhere from three days come a main without eating before difficulties arise. In fact, it’s healthy to skip a day here and there, to clear your digestion and also encourage them to burn fat reserves. For tiny fish with much faster metabolisms, you have the right to offer a single light feeding every so frequently for the same results.

If you have to leave unexpectedly for a two-day weekend, her fish will certainly be certain fine. Unless they are little fry, which need constant feeding. Yet what around if you must be away for more than a couple of days? It’s absolutely stressful because that fish to have their feedings interrupted because that a long duration of time.

How can I keep My Fish Fed during a Holiday?

Automatic Fish Feeders

Automatic fish feeders room my tool of an option for this situation. These tools store prepared foods items in a hopper and also can it is in programmed to dispense some as frequently or as small as girlfriend wish.

I extremely recommend having an automatic feeder top top hand a couple of days prior to your expedition so you can work the system out and ensure it operates properly. Some are only qualified of dispensing a single kind of prepared food (i.e. Only flakes or pellets) so pick carefully.


The Torlam is a more versatile design that comes with additional options for versatile operation. It can be calibrated come give dual or triple feedings at specific times of the day. For example, you deserve to program one come drop a small, solitary serving that pellets in ~ night for your plecos however give a triple feeding in ~ noon for the community.

And as soon as you return home, you can keep the unit installed yet use the manual override switch to have actually the pleasure of personally feeding your fish. However should company take you away, the Torlam Auto Feeder will certainly dispense food as normal.

Fish Sitters

Having a neighbor, relative, or friend drop by to feed her fish is one more common way to make sure your fish eat properly.

Fish sitters can also do points automatic feeders can’t, prefer remove a fish that’s died during your vacation so the doesn’t rot and cause further problems. Or call you to provide updates, send picture of the tank, and more.

I feel best if mine fish sitter knows something around aquariums so it’s great to it is in a component of a neighborhood aquarium society or have actually a partner that knows fish! people who aren’t acquainted with fish might underfeed or lot worse, overfeed.

As vacation feeders go, these products are okay. Castle are definitely the simplest means to store your fish fed over her trip. However, ns don’t use these myself and I would caution friend if you decision to buy one because that a few reasons.

Food block are essentially mineralized block of vegetable and animal protein. The mineral flour slows the release of nutrients right into the water. If this is a clever idea, the trouble is that the release is constant.

Once her fish stop eating the dissolution procedure continues. Manufacturers shot to balance this by lowering the nutritional content, which renders sense. Other than now we’re just giving low-quality food to our fish. Much better than nothing yet far indigenous ideal.

Also, plenty of fish won’t also recognize this blocks as food. Many ar fish, favor Guppies and Barbs, room pretty versatile and willing to pick at anything.

But i would issue using among these v fish accustomed come a big mouthful of food, like Cichlids. Tetras aren’t grazers either and also might not acknowledge a food block. So take into consideration your fish, their nutritional needs, and your vacation time carefully to decision whether this product is right for you.
