Because that way the ice ends up on top, leaving plenty of still liquid water for the fish to swim in.
The property of water that allows fish to survive winter's freezing temperatures is that the density of ice (solid water) is less than the density of liquid water. Because of this, the surface layer of water in the lakes freezes, and floats on top of the liquid layer, thus allowing marine life to survive.
they keep living in the deep unfrozen area The fish do not freeze or die in the frozen water they are still in there and swimming around or they could have found tunnels to move to a diffrent stream to swim freely in!
Fantail fish are cold water fish and can adapt to a wide range of temperatures. While they can tolerate cooler water, a heater may be beneficial in maintaining a more stable and comfortable temperature for them, especially in fluctuating environments. It is recommended to monitor the water temperature and provide a heater if needed to ensure the health and well-being of the fantail fish.
hahaha
If it hasn't got a filter you are limited to the type of fish that will live happily in your aquarium. In any case, use prime in the water to dechlorinate it and neutralise nitrate and nitrite. Without a fliter, you wont have your fish for long and will need to do daily water changes.
Water expands as it freezes so becomes less dense than liquid water. Ice floats to the surface leaving liquid water (for fish to swim in) below the surface ice.
As water freezes, it expands, becoming less dense. This means that the ice is on the TOP of the lake, and the fish are below the ice, in unfrozen water. If it were not for this property of water, lakes would freeze from the bottom up, killing the fish. Most things do NOT expand when they freeze.
If the water freezes but the pond is deep enough for the fish to still be in water at the bottom there is a good chance they will survive. If all of the water freezes however and the fish become frozen solid then I'm afraid they are unlikely to survive.
Put it in a bowl of water with a lid on it and place it in the freezer. The fish basically goes to sleep, and dies as the water freezes.
Freezes too. It is very difficult for a canal to freeze because moving water is not likely to turn to ice
No
I think you are probably talking about the fact that frozen water (ice) is less dense than liquid water, so freezing temperatures will enable the ice to form on top of the waterbody, but still allowing liquid water underneath so fish can survive. Also, ice is usually translucent, so it can still penetrate the ice, allowing algae to continue to photosynthesize, providing oxygen for the fish below.
Fish survive through severe winters because of the property of water that allows it to freeze from the top down. This means that even if the surface of the water freezes, the layer at the bottom stays liquid, providing a habitat for fish to survive. Additionally, fish can adjust their metabolism and hibernate to conserve energy during cold winters.
Fish do not travel in ice, fish travel in liquid water. Fish remain in the Southern Ocean even when the sea ice freezes from the top. There are no fish in the ice sheet that covers 98% of the Antarctic continent.
To change the water in a fish bowl, carefully remove the fish and any decorations. Pour out most of the old water, leaving a small amount to keep the beneficial bacteria. Refill the bowl with fresh, dechlorinated water at the same temperature as the old water. Reintroduce the fish and decorations back into the bowl.
How do I screw? Very well. How do I chop a song? I don't. How do you hotwire a car? That information is elusive for a reason. Can you overdose on weed? No. Where do fish go when the water is frozen? They go down deeper to where the water isn't frozen.
It freezes there blood. Which is cold blooded killing them from hypothermia. ( Might turn a color or sink to the bottom of the tank.)
