A healthy, grown-up aquarium fish can go from 3 days to 1 whole week, without eating any food. Some fish species can live for more than 2 weeks without eating. An adult fish can skip a couple of days without food if it has enough body mass and fat reserves.
The average lifespan of a fish in the wild is between 2 and 3 years, depending on the species. The length of time it takes to reach adulthood depends on a number of factors, including the size of the fish, the amount of food it eats, and the type of water it is kept in.
It can also be affected by environmental factors such as temperature, salinity, oxygen levels, water chemistry, etc. A fish that is fed a high-calorie diet, for example, will have a shorter lifespan than one that eats a more balanced diet. If you want to know how long it will take to become a mature adult, you can use the Aquarium Fish Calculator to estimate your fish’s lifespan.

Can fish survive without food for 3 days?
Most healthy aquarium fish can go three days to a week without eating. It’s not recommended to go more than a day or two without feeding the fish, as this can lead to them becoming sluggish and unable to move. If your fish is sick or injured, you may want to take it to your veterinarian for treatment.
Can fish live 2 days without food?
Many experienced fishkeepers routinely leave their charges for two to three days without making any provisions for feeding. Almost any fish can go that long without fish food (more about that later, as well). If you’re going away for a long time, some preparation may be necessary. The first thing to do is to make sure that you have enough food for your fish. If you don’t, you’ll need to find a way to supplement the food you already have.
This can be done in a number of ways, but one of the most common is by using a fish feeder. These are devices that allow you to feed fish directly into your tank. They’re usually made of plastic, and you can buy them at most pet stores or online. You can also use them in conjunction with a food dispenser, which is a device that dispenses food directly from the tank into the aquarium.
The advantage of these devices is that they’re easy to set up and take care of, so you won’t have to worry about them getting lost or damaged in the course of your travels. A good rule of thumb when it comes to feeding fish is 1/2 to 1 gallon of food per pound of fish, depending on the species.
Can goldfish live without food for 3 days?
Goldfish are able to go up to two weeks without food, but it’s not a good idea to leave your fish without food for a long period of time. If you are away for more than three or four days, make sure your goldfish gets its regular daily feedings.
Can I feed my fish once a week?
Feeding your fish once or twice a day is sufficient for most of the time. Some people fast their fish one or two days a week to make sure they don’t get sick. Smaller, more active fish can go longer between meals than larger, more sedentary fish.
If you have a fish that is very active, you may need to feed it more often. If you are feeding a large fish, it may be necessary to increase the amount of food you give it. You may also want to consider feeding the fish more frequently than once every two to three days.
What happens if I forget to feed my fish?
Fish can go a week or two without a meal without a problem in most cases. Fish in well established tanks can last even longer, since they are eating planaria and other bugs, live plants in planted tanks and almost any fish will try some algae out if it is in the tank.
If you have a tank with a lot of fish, you may want to consider adding a fish food supplement to your tank to help keep your fish healthy and happy. You can buy fish foods at most pet stores, or you can make your own by following the directions on the back of the food package.
Can you skip a day feeding fish?
Healthy adult fish can go for a week or two without feeding. Young fish can’t go without eating for a long time because they don’t have the fat stores of adult fish. Over a long period of time, your fish can be left without food if you skip feedings.
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. According to research, fish may be less active and less alert to danger. Some fish float in place, others wedge themselves into a secure spot in the mud or coral, and some even locate their food by smelling the water.
In the wild, fish are usually found in groups of two or three, but in captivity they can be as large as 20 or 30 individuals. They are also often fed a high-fat diet, which can cause them to lose weight.
