best male to female ratio for nasuta?

[riftjunkie]

Hi everyone. I have just acquired 6 "tiger nasuta" and am fairly sure I have 1 male out of the bunch. I have the opportunity to pick up another male to add to the group and am wondering if that would be wise. These fish are at 3" right now. I can also pick up two more females if I want. What do you guys recommend, a harem group with 1 male, or a group with two males. I have heard that males can be very aggressive toward each other. They will be in a 75 gallon for now.
