I got a good look at them today and noticed the black on the top of the head has a green shimmer in the sunlight and was wondering is the normal with both sexes or just males
Roughly. They look to either be coming out of a molt (7ish weeks) or going into a molt (10ish weeks). If they are going into a molt and one of them is male like they claimed then he will begin to change colors. But if they are coming out of a molt it will be a few weeks before they molt again. Or they might not molt again and that would put them at about 13 weeks and both female.
