Well, the more you get, probably the less they will concentrate on just one fish. I had one powder blue and one flame. The flame was going after the powder all of the time, so I brought the flame back. He annoyed me too much to deal with it. I then got 2 more powders. It seems to be in their nature to go after each other to some degree, but having 3 of them and of the same kind seemed to have made it better. They don't go after each other as hard as the flame would go after the other one. Poor guy. Anyhow, I would suggest getting 3-5 of them and hopefully they won't concentrate on just one and it should calm them a little I suppose. You prob. don't want 2 males and one female either. That would be bad from what I have read. Too much competition for breeding or whatnot. And from what I understand, the males are the more colorful ones, but you may want a moderator to back up that statement. Lastly, depending on your tank size you may not want to get too many of them. I suggest at least 3 with plants and stuff to get away from the other ones and that should work.
Would that account for the their behaviour? Should i get a rugged male to take their minds off each other?
