Australian Rainbowfish Gender Question

[Pamthefishfreak]

Does anyone have experience with Australian Rainbowfish (Melantaeniidae fluviatilis)? I currently have what I believe are 3 females (yellow-green fins and tail) and 1 male (reddish fins and tail). I am noticing aggression among the females if my assumption is true. Do I have the right idea about the genders of this species? Will it help to curb aggession if I get more of the males?


Thanks in advance.
