Additional Information
Miscellaneous Information: 

I decided to attempt raising this species because they are known to eat bristleworms. (I have noticed bristleworms eating clown's eggs so am looking for a natural control method) If these shrimp become too aggressive, I will move them to their own tank.  With a pelagic stage of over 5 months , it will be a VERY long wait for the fry to settle.

Since finding a mated pair proved difficult/impossible, I purchased four individuals online (site unseen). One was a gravid female and the other three 'appeared' to be male. Once acclimated, each was placed in a separate breeder net; then, I placed one with another and watched - ready with a net to remove one if they began fighting. Results: one died during acclimation (the largest shrimp), two faught, and two paired up with no fighting at all.

You will be required to provide photographic evidence in this thread of each event submitted for the MBI Program.
If your thread does not contain these photos the MBI Committee will not be able to approve your reports.

10-29 they eggs she was holding had turned white.  She molted the next night.

 
Here she is tending to the eggs

After her molt, she was significantly larger and a bit more aggressive to the male. They still stay within antennae length but if he gets too close she will jerk her body and he backs off... strange.  I was hoping she would develop more eggs but hasn't yet... maybe on her next molt. They are still in the small holding container so I can observe them closely. They eat a LOT for their small size!

 

Also, I was unable to find any fry that hatched. Maybe they ate them?

The female did not show any egg development or spawning after her last molt, however, I can see a dark green coloration within her carapace over the last few days. I assume she will spawn during her next molt and place the eggs under her pleopods.

Very cool (and great pics of the eggs!) I might have missed it, but did you get them as a pair or just put some together?
 
Thanks!

I very carefully created a pair by ordering four individuals. See above quote.
I'll try to get more pics of her tonight so you can see her green carapace.

Right after I typed that I re-read the beginning
 
Thanks so much!
 
Oh and by the way, Sealifeinc.net carries pairs of lots of shrimp (and other things too)
 
http://sealifeinc.net/catalog/index.php

 

They collect from the Keys in Florida.  Usually 2-3 times  a month they have shrimp pairs. (Looks like they are out now)

Thanks for the info. It's good to know if I ever need to replace this pair

Here are some photos I took today.
You can see the green prespawn eggs well.

 
The male daring me to mess with them one more time.... LOL

This is strange... I checked the pair this morning and noticed one had molted. I did not think it was the female because I could still see a green mass in her carapace.
I checked the pair again about 2 hrs later and the female had moved the eggs under her abdomen!  They must mate early morning post molt.
 
Here are a few photos of her this morning:
