One of my red eared sliders is vibrating its hand in the others face whats it doing???

Males have very long claws/toenails on the front feet and they "flirt" with females by placing their paws in front of their face and doing just exactly what you are describing. Males MAY do this as a sort of "hand jive" with other males as a stylized form of a dance in lieu of real and possibly fatal attacks.

Reply:snake_girl85 is correct again.


If one is trying to dominate the other you may have to separate them as the weaker one may be attacked or bullied to the point it will not get enough food.

Between two males, it could be a territoriality display, or it could be a result of the stress of a too-small tank.

Reply:they're trying to mate. even though one is a boy, if no females are available they get umm... less picky about who they romp with. Are you positive that they are both boys?
Reply:Males have very long claws, and it's either a mating ritual or a dominance display, depending on what the other turtle is.





EDIT: Both males means dominance display... just watch out for aggression
