good luck, maybe also try giving them plenty of cover/floating plants/moss to make them feel safer? berried shrimp usually only drop when stressed, scared, or moved......
Thought id give you all another update, I have had some more success touch wood.
There are now lots of little shrimplets getting around in my tank.
Hard to say how many but on one count I managed to see 9 all at once. I just hope now they can survive, grow and then the girls will do their thing and give me more.
