Check the temperature and make sure the water is not too hot (heater defective?), check the pH and also the hardness and make sure they are within the parameters needed for your fish. Change 1/3 of the tank's water. Check the filter and make sure it is not plugged up with a lot of food and poop. Rinse the filter in warm water (same temperature as the water in the tank) so you do not kill off the good bacteria which keep the water clean. Check Nitrite(toxic) and nitrate (not toxic) levels. All this should help you ensure the perfect environment for your fish. If you do not have way to oxygenate the water you may want to extend the return pipe of your filter to the surface or above the surface of the water in order to make it integrate oxygen from the air.
