I think I finally have the tank at parameters the shrimp like. I haven't had a death in a week and I have a barried shrimp. She is pretty young so I don't think she will carry them full term but I'm excited she is comfortable enough to become barried.
I put two Indian almond leaves in my CRS/ yellow tank a week ago. They don't really eat them but today I noticed three berried CRS in the tank and I've had them for months with no luck
