Fish weigh less in water because of buoyancy, which is the upward force exerted by a fluid that counteracts the weight of the object immersed in it. The water exerts an upward force on the fish that partially cancels out the downward force of gravity, making the fish weigh less in water than in air.
Because sea water is more dense than regular water
No, body fat does not weigh more than water. Both body fat and water have different densities, with fat being less dense than water. This means that for the same volume, water would weigh more than fat.
You would weigh more in the air than in the water due to the buoyant force acting against your weight in the water. In water, your body experiences an upward force opposing gravity, causing you to feel lighter. This effect makes you weigh less in water compared to being in the air.

The balloon fish will float because it weighs less than the volume of water it displaces. By swallowing air, the fish increases its volume without significantly increasing its weight, allowing it to float at the water's surface.
That depends on the weight of the fish as compared to the weight of the water their bodies displace. If it's a heavy, dense fish, then the tank with the fish would weigh more. If it's a light, less dense fish, then the tank with water only would weigh more. This assumes that the water displaced has been removed from the tank, right? If you are adding the fish to the water then I think it should increase the weight regardless of the density of your fish. The question then might be, does the fish weigh less when it is swimming than it would on a dry scale?
im guessing less than a pound
no
No. Oil is less dense than water, so 1 liter of oil will weigh less than 1 liter of water.
Less than Rhino Poo, more than the Fire Ant.
Its density
They weigh less than the water they displace.

No, gasoline weighs less than water.
