Why are those guys in the videos touching and tugging on the coral?

Quite certain that's a no-no, and setting a terrible example for others.

For reference, see "Coral Etiquette" [0]:

    Simply touching corals to see
    what they feel like can cause
    the death of an entire colony.
    Oils from your skin can
    disturb the delicate mucous
    membranes which protect the
    animals from disease.
