Is there any way to sex juvenile Gold JDs? I've seen pictures of ones that were claimed to be females with the tell-tale blue beards that normal JD females have. Is that the case with Golds as well? My LFS has about a dozen Golds at about 2" and not one of them has a blue beard, but I find it hard to imagine that not one of them is female, unless the supplier removed all of them or someone came in before me and bought all of them. Anyone with experience know if all female Golds have a blue beard or any other way to tell?
