Happy to hear that your female is giving birth and all is well. Its good that you can't see them all, it means the fish can't see them all either. It will lead to a higher survival rate. I am going to try to attach 2 pictures if I can figure it out. The first is a red wag platy female. The second is a red wag male. The difference is obvious between the male and female anal fins, that is the fin about halfway back on the bottom side of their body. Here goes nothing.
