But I call them all boys until they show me traits of being girls... as the vast majority I've raised have turned out to be boys... although I haven't been breeding them long enough to have had any of my spwans reach sexual maturity (or even close).
well i bought a 2" jd a few weeks ago and she s the same size very blue gills and the blue dempsey flaired his gills at her and then like they swim together now and everything i also had a bigger female and the one i bought a few weeks ago and her fought over the blue one and they stayed a trio for a bit then the bigger female just ended up swimming alone all the time .. ehh ill find out one time soon
