Most fish simply school in the deepest pools and take a “winter rest.” some species, like gobies, may burrow into soft sediments and go dormant, but most fish simply school in the deepest pools and take a “winter rest.”. In the wild, however, fish can survive for months or even years without food, water, or oxygen. They can even survive without oxygen for weeks at a time.
In fact, some fish have been known to survive as long as a year without water or food. This is because fish are able to use oxygen as an energy source, which allows them to stay alive for long periods of time, even when they don’t have food or water.

How cold can fish live?
Outside of their optimal temperature range, fish have to make adjustments to their body temperature to survive. Temperature is the most important factor in determining the survival of a fish. It is important to remember that temperature is not the only factor that affects fish survival. For more information on these factors, please visit our Fish Health page.
Are fish resistant to cold?
If you plan to stock your pond with fish and hope to have them survive the winter, be aware that if your pond freezes solid from top to bottom, no fish will survive, no matter how cold-weather hardy they may be. If the bottom of the pond looks like it has frozen over, you have a frozen pond.
If the water is crystal clear, it is not frozen, and you should be able to see through the ice to the surface. You can also check the temperature of your water by placing a thermometer in a cup of water and placing the cup in the freezer for a few minutes. The water will be warmer than it was when you put it in, but it will still be below freezing.
How do fish stay warm in the winter?
Because ice is less dense than water, ice forms on the surface and provides some insulation to the waters below, keeping the fish warm. The gills of fish allow them to breathe through the water. Ice is also used as a food source for many animals, such as seals, sea lions, penguins, and whales.
Can fish freeze and come back to life?
Sometimes the answer is yes, sometimes not. When the weather warms up, some fish can spend the winter in ice and come out swimming. The reason for this is that the body temperature of fish is much lower than that of the surrounding water. This means that when the water temperature rises, the fish will not be able to keep up with the rising temperature, and they will freeze to death.
Do fish ever fart?
Most fish do use air to inflate and deflate their bladder to maintain buoyancy which is expelled either through their mouth or gills which can be mistaken for a fart. Sand tiger sharks excrete out the back door of their mouths when they gulp air into their stomachs at the surface. In addition to air, fish also use a variety of other gases including nitrogen, oxygen, carbon dioxide, methane, and carbon monoxide.
Nitrogen is the most abundant gas in the ocean and is used by fish to regulate their body temperature. Oxygen is a by-product of photosynthesis in plants and animals. Carbon dioxide is produced by the burning of fossil fuels such as coal, oil and natural gas. Methane is an odorless, colorless and tasteless gas that is released from decaying organic matter. It is also produced from the breakdown of plant and animal waste.
Can a fish survive in milk?
Over millions of years, fish have evolved to survive in water with a certain amount of dissolved oxygen, acidity, and other trace molecule. Even though skim milk is nine-tenths of water, it still wouldn’t be enough to support a healthy fish population.
In fact, a recent study published in the Journal of the American Veterinary Medical Association (JAVMA) found that the average American diet contains more than twice as much saturated fat as is recommended by the U.S. Department of Agriculture (USDA) and the World Health Organization (WHO) for healthy adults.
In addition, the USDA’s Dietary Guidelines for Americans (DGAs) recommend a daily intake of less than 10 percent of calories from saturated fats, but the study showed that American adults consume an average of nearly 50 percent more of these fats than the recommended amount.
The study’s authors concluded that Americans are eating far too much fat in their diets, especially when it comes to dairy products, which are the most commonly consumed dairy product in America.
Do fish get lonely?
Goldfish are just not the same as humans – they’re not social animals in the same way that we are, and they don’t have the same capacity to get bored or long for companionship. Many of the longest living goldfish have been kept alone, with no obvious harm to their health or well-being.
Goldfish can be kept in a variety of environments, including aquariums, tanks, ponds, lakes, rivers and streams. They can also be housed with other fish, such as snails, slugs, worms and other aquatic invertebrates. Some species of fish are more suited to captivity than others, so it’s important to choose the right fish for your aquarium.
Do fish have feelings?
“It’s just that they don’t have the capacity to express them. It’s like a child learning to speak.
