That's natural behaviour. Usually it's directed at other turtles/fish in the tank. In your case he's just discovering something new in his home and showing the new 'friend' who's boss.
When a turtle behaves that way towards another turtle, it can be a territorial issue, or part of the mating ritual.
Both my turtles do this to eachother, fish, and new items in the tank.
