Naw the 12 months I think my problem was all I had were males, or they didnt like the tank. I put like 12 from my 55 before my discus went in that tank a couple years ago. But none of the shrimp ever seemed to berry up.
I got 12 From ghost shrimp sakura grade juvies about 1.5 months ago, I also had a group I got from another member who got out of the hobby around the same time. About 2 weeks ago after quarintine I moved them in to the 20, I have around 40 shrimp in there after I combined them. And now have berried females! I am hopeing they dont drop there eggs but they should be fine. Will keep you all posted and try to get some pics tonight.
