Just bought a new clown, how long before the bigger one stops chasing it?

Well about 2 months ago we lost one of our clowns, until now we were not sure if we wanted another, and today we decided to get one, another Percula, it is about half the size of the one we have. Now ever since we put him in the tank the bigger one has done nothing but chase the little one around. We did turn the lights out early and things seemed to have calmed a bit, but is this normal or is this a sign that they will not make good tank mates?

We also got a pictilis anthias that is really pretty and he has not done much since we put him in the tank. But my biggest worry is the small clown, I kinda feel bad for the little guy. If anyone has any advice on how long this might last or if this is normal please I would love the advice.
