Wow! You guys here are really helpful and it is much appreciated
My next question is at what size are you able to start sexing Royal Whiptails?

About 10cm/4" total length [not counting fin filaments] or so, in general - perhaps a bit larger for the species that grows a bit larger than the "commonly available" .
