A number of years back I got a berried one from the lfs and it had babies after a little while in my Red Cherry shrimp tank, the nano 6.6G, lots of them, but I am sure they ate each other as well as loosing the weak ones, I had about 8-10 decent size 1/3rd inch, then they all seemed to disappear except mom and baby and then baby was the only one left. Since my RCS babies had also been eaten I rehomed him.
Good luck with getting a berried one or 2 - would separate them out if you are going try to produce babies for sale. They are great.
The really blue ones are pretty cool but haven't seen them available around my lfs.
Would love to see pics of your new additions.
