Hello; It has been over 40 years since I fooled with these fish but I will hazard a guess. bear in mind I may be very wrong or at least 50 % chance I am wrong. I use to go by the dorsal fin. Best I can recall if the dorsal fin ends in a point it is male. If more rounded then female. I think male. I know this is not universal and you should wait for others to chime in.
 
More torpedo like shape has me thinking female along with the more inverted cloaca for the top picture. And male in the bottom pic. I could also be wrong. Very hard to sex
 
Today i noticed they’re egg inside this ship.the bottom fish(dark blue) is guarding those eggs.below are my latest picture of my fishes.
