I believe this is the appropriate place to post this if not just delete or let me know. I inherited 7 of these polar blue or HRP I’m not sure what the most accurate name for them is, a few days ago I noticed their behavior/colors changed it seems like 2 maybe 3 pairs are attempting to breed or at the very least courting… one pair laid some eggs but as far as I can tell they weren’t fertilized. I have pictures and some videos is there anyway to sex them? I’ve seen different sites some say the males fins are more pointed/longer, their tales have a reddish color, they’re smaller… I just wanted to know if there is a way to verify, I was hoping to let 2-4 pair off and sell the ones that hadn’t paired off. But if they haven’t pairs off soon I don’t have much more time as they’re growing and I don’t want to stress them, so in that case I would keep 2-3 females and 1 male or all females to reduce aggression. Which hasn’t been an issue. Just hoping someone would be willing to look at some videos or point me in the right direction?
