While I'm not acutally planning on breeding anytime soon I sometimes amuse myself by hypothetically guessing what x female and y males fry would grow to look like. [Since genetics fascinate me]
Well looking at two [my male my GF's female] I was struck by their sheer size difference. So it got me thinking... when picking a pair [when not using siblings] do you try to get decently close sized fish rather then teeny female and huge male or does it not matter? [Assuming the male isn't too vicious and won't brutalize her]
Just curious c: I like to know as much as possible if I do one day decide to do this.
