You may continue to see aggression from the male. At that point I would continue to add females until the aggression is reduced.
When I first started the hobby I didn't know what I was doing and went and pointed to fish cause they were pretty and the guy at Petsmart "guessed they should get along fine." After sorting things out, rehoming a few fish, upgrading my tank size, and researching here on Aquarium Advice I couldn't get to the store fast enough to get more females! I had one female and one male and she was pestered every waking moment.... I came home with two more females and he was much happier... as were his little ladies
