Here is a picture of one of them holding eggs:
    Sorry about the low quality but you can still make out the eggs under the pleopods. Looks almost like a black shade.

The other one is now pregnant as well, I will be setting up the larvae catcher in the tank tonight in case the first shrimp releases her eggs.

Here is a better photo of a pregnant female:
 

It's been 4 days since the other shrimp held her eggs, I'll try and snap a photo of her but her eggs already have...eyes? Little black dots all over the place. And a considerably less amount of eggs than the other shrimp. I will set up the larval catcher tonight and see what happens.

I think that's pretty dang cool: A snail with multiple larval development patterns based on environmental cues
