No, it doesn't since water is all around the fish and puts pressure from everywhere just as air puts pressure on us everywhere. But if the fish is the floor then it would be heavier since there is no pressure.
Yes, a fish has weight in water due to the gravitational pull acting on its mass. However, the weight of the fish in water is offset by the buoyant force exerted by the water, which helps keep the fish afloat.

Yes, fish do add weight to the overall weight of the water in a pond. This is because the fish has mass, which adds to the mass of the water. As the fish swims around in the pond, it displaces the water in the pond, which adds to the overall weight of the water in the pond. Furthermore, when a fish excretes waste or urine, it adds to the overall weight of the water in the pond. The additional organic matter in the water, such as food particles and other organic materials, also add to the overall weight of the water in the pond.
A gallon of water weighs about 8.34 pounds. If you have a good sized bucket with a gallon of water in it and you put a 5-pound fish in the bucket, you'll have a bucket that weighs about 13.34 pounds (plus the weight of the bucket). That's as long as the bucket doesn't overflow. The fish will (usually) be neutrally bouyant in the water, and it will be essentially weightless in that water. But its weight will add to that of the water in the bucket. No, it won't weigh 15 pounds, but it will weigh in as suggested. However, the weight of the water itself will not change.
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?
put the live fish in a bag filled with water and change the tank then put the fish back in.
If its outdoors mayby theres an imbalance in the water, with the levels of alkaline.
well if its cold water fish then 3-4 days :)..
When you are changing the water in a fish bowl, you have to empty cup ot bowl with water in it. Then, put it into clean water.
It depends on if you are doing a complete water change or a partial water change. I usually just leave the fish in and siphon off about half of the water than replace the water. The fish get a bit nervous but seem to be fine with being left in the tank. To answer your question: No, you do not have to remove the fish when changing the water.
falcon, because a falcon is a bird.
