Male guppy have the pretty Ionger tail females short tail . So if yours has a shorter tail than it is a female but it has a longer tail the orange part but it will be a male I always looked at the bottom part of the belly of guppy if it's black spot pregnant .
The way I tell if a female is pregnant look at her belly is there a black spot inside ? The bigger the black spot the father long she is when belly full she has them soon. If she's upside down sometimes she's sick. I used to bread guppys
