Depends, the figh either leave or die.
leave it out of water.
Who knwz ... :P
At least 1 week, test your water before you add any fish, you may need to leave it for longer to allow the ammonia level to come down. I had to leave mine almost 3 weeks.
If they are in a tank, make sure they are fed and the water is clean. To clean the tank, remove the fish and put them straight into another source of water. Remember if your fish is salt or fresh water. If the fish is in the sea, river or pond, its best to leave it. If the fish is on land near a water source, replace it in there. If it is nowhere near a water source, I have no idea how it got there. You would have to leave the fish then. Sorry if this answer is vague, because your question was as well.
fish are developed with gills so they need water in order to breath.
the fish needs to be in warm water that is just right. then leave the fish alone in peace and it will be fine.(:
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.
because it has gills that filter out the water and leave the air.
u leave it on the floor and let it suffer by jumping on it
Leaves give oxygen, leave are in water. Such as algae, therefore you have oxygen for fish.
The general rule is that one should change around 25% of the water at a time, thus all you need do is leave your fish in the tank and siphon out 25% of the water, and then replace with dechlorinated water of the same temperature. If you are cleaning a bowl, then it is more common to clean the entire bowl; in that case the fish maybe be placed in a bucket or cup.
Pollution comes from the Latin for "to make dirty". It has this meaning today
