Hi! I have noticed a recent appearing of a tiny black line on the gonopodium of one of my male blue and black Platys (see attached photo). I have been researching all kinds of worms, pests and parasites, and have found nothing that looks like this. Is it likely just a color spot appearing as he matures and colors up, or is there some pest I am missing that looks like this???
