You are watching: How long can a fish go without eating

If there’s nothing we deserve to do and we need to be gone for a spell, just how long have the right to fish go without food?

How Long deserve to Fish go Without Food?

Most healthy and balanced aquarium fish can go 3 days come a week there is no eating. However, it normally isn’t encourage to go an ext a job or two without feeding unless completely necessary.

This number might vary based on a few factors:

How active Are your Fish?

How lengthy your fish deserve to go there is no food depends greatly on the management of your fish. Smaller fish tend to be very active, which method they need more food 보다 slower, larger fish.

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

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

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

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

Are your fish herbivores or carnivores? due to the fact that plants have tendency to it is in abundant yet low in nutrition, herbivores have tendency to graze continually. Castle need big amounts that this lower energy food to maintain their weight. Carnivores, on the other hand, deserve to eat a solitary meal and also digest because that a longer duration without eating.

How huge Are your Fish?

Body mass is simply as essential as metabolism and also for plenty of fish the two are very closely related. Typically speaking, bigger fish have slower metabolisms than smaller ones. However, larger fish additionally need much more food to maintain their body load than smaller sized ones, therefore it’s a trade-off.

As a rough dominion of thumb, bigger (adult) fish have the right to go longer between meals than smaller ones. In fact, adult fish with slower metabolisms favor Goldfish really only should 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 just how much they were fed earlier. Not just does their metabolism slow down as they age yet they are likewise cold water fish.

While friend shouldn’t shot to check this, most fish deserve to go everywhere from three days come a main without eat before problems arise. In fact, it’s healthy to skip a day here and there, come clear their digestion and encourage them to burn fat reserves. For tiny fish with much faster metabolisms, you have the right to offer a solitary light feeding every so regularly for the same results.

If you must leave unexpectedly for a two-day weekend, her fish will be absolutely fine. Uneven they are small fry, i m sorry need constant feeding. However 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 period of time.

Automatic Fish Feeders

I very recommend having an automatically feeder ~ above hand a few days before your expedition so you have the right to work the system out and also ensure it operates properly. Some are only capable of dispensing a single form of ready food (i.e. Only flakes or pellets) so pick carefully.


The Torlam is a much more versatile version that come with extr options for versatile operation. It deserve to be calibrated come give twin or triple feedings at details times the the day.

Once her fish avoid eating the dissolution process continues. Manufacturers try to balance this by lowering the nutritional content, which makes sense. Other than now we’re just providing low-quality food come our fish. Far better than nothing however far indigenous ideal.

Also, countless fish won’t even recognize these blocks as food. Many ar fish, prefer Guppies and also Barbs, are pretty versatile and willing to pick at anything.

But i would concern using among these with fish accustomed come a big mouthful the food, choose Cichlids. Tetras aren’t grazers either and also might not recognize a food block. So take into consideration your fish, their nutritional needs, and also your holidays time closely to decision whether this product is ideal for you.
