My 220 litre high tech has been running 4 months now. About 1 month after setting up I started adding shrimp and fish. Right now I have;
About 40 amano shrimp
Dozen crystal shrimp
Dozen nerite snails
Half a dozen otos
Dozen CPDs
Half a dozen emerald line rasbora
30+ Espei rasbora
20+ Pascai rainbows
Half a dozen threadfin rainbows
Approx 100 cherry shrimp
I initially added approx 20-30 cherries of mixed sizes (young and adults) including a couple of berried females. Over the course of the first few weeks post more and more females were berried and at one point I think I counted 10 individuals with eggs, then no long later I noticed tiny babies everywhere. These babies have grown and I now have probably 60+ which are between 0.5 and 1.0cm long. So all in all this is great news
The bit I'm confused by is that the number of big adults seems to have reduced. There are loads of juveniles but the adult numbers have shrunk (either that or they are doing a fantastic job of hiding). I also haven't seen a berried female for a month or two
Now the shrimp are clearly thriving in some respects as numbers have definitely gone up noticably but at the same time I seem to be missing adult breeding stock. First thoughts are that something might be predating on them but if that were the case the younger ones would surely be first pick. Second thoughts are that it is a molting issue and I'm losing some during that process but according to Google they molt every few weeks, so therefore some of the young must be molting too, so why aren't their numbers reducing. Final idea is that maybe the amano's are picking off the adults, why only adults though makes no sense
Anyone got any ideas?
