I have had them for a few months, they were berried when i bought them, which i found perfect! They are like ghost shrimp and don't give live birth, they birth larve which i couldn't keep but I am sure with tons of plants in a nice tank they might live long enough to be adults! who knows, all I know is they are beautiful and fiesty! I got them at 2 different times at the same place that were in a ghost shrimp tank, now I did see them berried after their 1st time, maybe from a ghost shrimp possibly, u could give it a try, be careful with smaller shrimp they could eat them if they are hungry enough.
