Additional Information
(No Pictures or Videos in the Section Please)
Miscellaneous Information: I put this pair in a 10 gallon to purposely try to rear them.  My first attempt at pairing was unsuccessful and the smaller of the 2 shrimp had to be relocated to my display tank. For the second try I acquired a shrimp of similar size to the first and placed them in the tank together but used a tank divider to keep them separated for 3 weeks prior to combining them.
The first spawn resulted in the mother molting without releasing the larvae into the water column.  The second spawn resulted in a release of about 15-20 larvae.  I am hopeful the next spawn which should hatch around 12/22/23 will be more successful.

The morse code couple, Dot and Dash.  This was my easy way of telling them apart in the beginning since they are of similar size.  The two white spots are so close on Dash's back that they are touching and look somewhat like a line instead of spots. 
  
Dash is who carrying eggs if you look closely.

Eggs that didn't hatch and I pulled off of the molt.

 
A few of the ones that did hatch on the second try. Taken at 20x with a dissecting scope, you can see regular old L strain rotifers in the background.
