Welcome to FishLore. Please stop by the welcome forum and introduce yourself. Let us welcome you properly
Now if you would give us some information please. The size of your tank and what kind of fish you have . If you have a water test kit it would be very helpful to know your ammonia, Nitrite and Nitrate readings.

Welcome to FishLore! It's great to have you with us! Usually when fish gasp at the top of the tank, they are not getting enough air. That's why we need to know a little more about your tank. You may have high ammonia or nitrite, or there's just not enough air water exchange, which can easily be fixed with an air stone. If your tank has too many fish in it, that's another problem, but we need to know more about your tank and what's in it.

Please take a sample of your water to your local fish store, and have them check the ammonia and nitrites. If you can get test kits for ammonia, nitrite, and nitrates, that would help out a lot in the long run. How much water do you change out every week? And when you change the water, do you dechlorinate, or do you have water that doesn't need to be treated?

my tank is a small one, so I change the water once a week besides, I take a cup of water from the tank and put another fresh one everyday.
every week after I clean the tank and fill it with water I dechlorinate it.
