Is this a proven pair? ie had wigglers?

[Reefwonderspa]

They have had wigglers/fry in the past before I got them, and have laid eggs but everytime that they do im not around . So im trying to figure out which is which, hoping the photos are good.

+1 The best answer anyone can offer.
In other words 50% female 50% male is my guess.
