Allen:
I love to play this game so I will play with you. It is too early to tell so I am guessing to see how it comes out.
Right now I would guess:
#1 I'd give 55:45 its a female
#2 65:35 female
#3 65:35 male
Please keep updating! I want to see how they come out. I think we will be able to tell by about 600g for a faster growing platynota.
Thanks for playing!
I suppose I should lock in my guesses:
# 1 M Based mainly on slower growth.
# 2 F Based mainly on faster growth.
# 3 M. Slower growth and anal scutes look a bit male to me.
My experience has been that males and females grow pretty much at the same rates (IF I really pick apart the charts, after the fact, the males do grow a little bit slower but its not that noticeable) until about 900g - 1000g. Then the female take off and grow much faster.
I agree the anal scutes look more male on #3, but from above, #3 has the most female shape!!
Very nice growth by the way. They look great.
I have had males start flashing me as early as 300g and only about a year old. However, I have had some that look female up until 600-700g before they flash me. So I would wait until they are around 800g or so before calling it a female.
I have now had these guys for one year. They seem to have done well and are at least 10x the weight of their first weigh in on the day after I received them.
