Grow-Out Tank Details Temperature: Size of Grow-Out Tank: Substrate Details: Other Tank Decor: Filtration Details: Lighting: Lighting Cycle: Water Changes: Size at Transfer: Age at Transfer: Grow-Out Feeding Details Food Types: Feeding Schedule: 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.
