Is he dying or is he just sick?
It is a sign of swim bladder disease.
Begin treating him by fasting him, no food, and lower the water level so he can easily get air
search the disease thread for more info how to treat swim bladder disease and it is likely you can cure him http://www.bettafish.com/showthread....ladder+disease
also in a small tank it is necessary to do frequent water changes, say every three days for a one gallon, make sure the water is the same temp. and that you use water conditioner
