if you wanna duplicate the same flame of the others candles, just use the photoshop 7 or CS clon tool... duplicate it on another layer and manipulate the movement with the liquify tool. if that's what you wanna do... if you want to create a brand new one, I recomend the Eye Candy 4000 FIRE effect, believe me you can manipulate the flame the way you want.
anyone with a better idea?
