bennyp do water changes of 10% everyday for 2-3 days and see what happens. Is your tank newly setup? If it is, might be ammonia level or nitrite level high...but only one fish is affected..might be gill flukes or some disease. Try to look up books or info on the net on fish disease syptoms and add the appropriate medication. (Water change first and see how is the fish cause medication does have its cons). Good luck.
