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: Maybe you haven't changed the water in a while and your fish isn't use to th new clean environment, maybe you changed too much water, or the fish is uncomfortable.
put the live fish in a bag filled with water and change the tank then put the fish back in.
well if its cold water fish then 3-4 days :)..
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.
Yes some fish do. They push themselves out of the water and then they walk around with spikes on their body for a while. However they have to go back into the water after a while.

If there is no overflow of water, then the container's over-all weight goes up by the weight of the fish. The weight of the water itself doesn't change.
Every month.
Not really salt water fish can adapt to fresh water but it will take a while.
take the fish out and then dump new rocks on top after dumping the water out.. put the fish in a bag filled with water. this job could be difficult if you have a large amount of fish. it depends on how many fish you have
no as long as there is water conditioner/ purifier in it
No because when you change water it is the same as in the wild where the water level go up and down. So don't be scarce to change water because it is a important part to keep your fish alive and healty. Hope that help!!!!
