The one that is moving about the tank is likely the dominant one. The fish are still new though, so it's too early to really say anything about their behavior. Typically though, aggression is felt before it's seen - outright attacks are the last stage, not the first. The lesser fish will try to avoid and submit to appease the dominant fish. This may work for a period of time.
