to pass on dragon dance but the daycare said they don't like each other
That doesn't matter. As long as the Day Care Man doesn't say that "They prefer to play with other pokemon than eachother," then you'll be fine. Also, Gyarados has to be Male and the Charmander has to be Female in order for the move to be passed on.
