As for food, freshwater fish are quite capable of going for several days without a meal. Adult fish can go without food for a week or two. Young fish cannot go without food for long periods of time because they don’t have the fat stores of adult fish.
If you want to feed your fish, it is best to keep them in a tank with plenty of fresh water. Fresh water is the best way to do this as it will keep the fish healthy and happy.

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.
Do fishes cry?
livescience. They don’t produce tears since their eyes are constantly crying. The study was published online today (Jan. 19) in the journal Proceedings of The Royal Society B. .
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 simply rest on the surface of the water.
Some fish, such as the Pacific bluefin tuna (Thunnus thynnus) and the Atlantic cod (Gadus morhua), are known for their ability to stay awake for long periods of time. These fish have been known to sleep for up to 24 hours at a time, which is longer than any other animal on Earth, including humans.
Can fish survive 4 days without food?
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 in an aquarium has enough body mass and fat reserves to skip a couple of meals once in a while.
The answer depends on several factors, including the size of the fish, the type of food it eats, and the amount of time it spends in the water. The average lifespan of a freshwater fish is about 2-3 years, depending on the species. In the wild, most fish live to be about 10-15 years old, but some can live as long as 20 years in captivity.
Can fish go 3 days without food?
Most healthy aquarium fish can go three days to a week without eating. Unless the fish is sick or injured, it is not recommended to go more than a day or two without feeding. Aquarium fish are carnivores, meaning they need to eat to survive.
If you are feeding your fish a diet that is high in protein and low in fat, they may not be able to properly digest their food. This can cause them to become ill or even die. Feeding a high protein diet can also lead to overgrowth of algae, which can be harmful to the health of your aquarium.
Can I feed my fish once a week?
Feeding your fish once or twice a day is sufficient for most. 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.
