It depends on the type of fish.Some fishes are sensitive to water but if it's a regular fish you would change it about 1-2 times a week
put the live fish in a bag filled with water and change the tank then put the fish back in.
You should change the water in your fish tank every 1-2 weeks to maintain a healthy environment for your fish.
Your fish will be much happier if you change at least 50% of the tank water every week.
You simply call it whatever you wish to call it. I have a fish tank called Claud.
You should change the water in a fish tank regularly, typically every 1-2 weeks, to maintain a clean and healthy environment for the fish.
"fish bowls" are not designed for fish regardless of how they are marketed; you should not keep fish in anything smaller than a 10 gallon tank.

assuming you have any fish left, test your water. do a 50% water change immediately. change your filter, it means there is something definitely wrong with your tank what are the details of your tank, size capacity, how many fish etcc

The size of the tank has no effect on how often the fish should be fed. All fish should be fed at least twice daily but only as much as they can eat in 15 minutes. The size of the tank does have an effect on how many fish it will hold. A 10 gallon tank holds that amount when filled to the brim. Under normal conditions it will never be that full so it will only contain about 8.5 gallons. The maximum amount of fish you could hold in there, if you have a permanently running cycled filter and change 50% of the water every week is about 8 inches of fish. Definately no more than that.

It is generally recommended to perform a 10-20% water change in your fish tank once a week. However, the frequency could vary depending on the size of the tank, the number of fish, and the stability of the water parameters. Testing the water regularly can help determine the appropriate water change schedule for your specific tank.
