I bought 10 yellow shrimp 1,5 years ago for my 40L and they started breeding immediately (funny to watch, the race of the males and the tiny babies). The population grew to perhaps 60 shrimp in just a few months. During that time, I added CPD's and some time later the breeding stopped. I didn't see shrimplets for months and I think the population has now shrunk to maybe 30-40 (just an estimation, no way to count them).
So, considering a life span of a shrimp and the fact they are not reproducing, I decided to select the nicest ones and move them to my 45L QT, now called "project tank", hoping they would breed. While there we still fish in this tank, a couple of females berried, but seemed to lose their eggs (only one survived to adulthood). The fish moved more than a month ago and since then there are only shrimp (±12) in the tank, but still no eggs nor shrimplets. Some of the females have HUGE saddles for while now...they molt well and seem to grow much better than they did with the CPD's, so I don't think they are very unhappy there.
What are your experiences on these shrimp? Any ideas? I read conflicting stories in the internet, they should breed well but there are people with issues too...PH is around 8, the temperature is ± 22C. GH 8. No CO2, quite some plants on decor and floating and a thin layer of black gravel. I fertilise well (EI macro's + Easy Life Profito) mainly to keep the limnobium healthy. I just don't know what the shrimps are missing. Maybe I have been too enthusiastic when selecting on colour and ended up with more females than males, but I am sure there are a few in there...
