Neither of my adult male and female has thatCan’t tell from the first couple of vent pictures as they are not focused on the vent.
In the other pics I think male as the papilla looks pointed
All fish have papilla, sometimes it’s more noticeable than others. You can see it when they are ready to breed.Neither of my adult male and female has that
Thanks but I’m hoping it’s a she as it was the slowest growing one and took more of the red from the mum. Dad is more pink with pearls.Hes VERY pretty!!!

Fingers crossed for you for a female.Daam well this one with its mouth pointed to the left the papilla is thin and pointy but it doesn’t seem curved it’s more pointed to the right. Time will tell I guess. So far it’s growing really slowly even doh I’m feeding it Bio Gold+ and Okiko Platnium. I read that females grow slower than males too. Really hopes it can be a female to replace my adult female. This is the pair.View attachment 1431392
The juvenile is in a tank on its own however I tried placing a divider with my male and the baby in the first week, same day I removed the divider as the baby was swimming normally on his side . Baby kept running from my big male. Whenever the big male comes to investigate the baby automatically runs so after a half hour or so the big male left it alone and was functioning perfectly fine without checking the juvenile and the juvenile just kept hiding.Fingers crossed for you for a female.
if it is a male and living with another male it might also slow growth and try to look more female as it isn’t the dominant fish
