Haha so im not the only. :)
Maybe some genetic ?
I dont have problems with the shrimplets grow or keep them , but why shrimps stop when rich a number, and dont begin again.
I dont have big tanks its around 30-40lt.
I try diferents substrtates, seachem , gravel, gravel with aragonite , akadama, all had the same results.
Raise temp to 26-27c.
Big -small water changes .
Adding seachem discus mineral.
The last time i moved to a new tank 170shrimps , no sandle no eggs.
My lights is 12hours.
Before i was keep them at :
Kh 3
Gh 5
Tds 140-160
I have co2 in the tanks my ph is about 6.7-.6.8.
Now i raise the gh wiht salty shrimp at 8-9 and tds to 180.
I see a lot of molts , and shrimps get biger,males going crazy. :)
I dont thinks that water parameters is the problem.
In all parameters shrimplets survive and grow but after population increase , shrimps stops breeding and sadle.
I put 10 of them in crs tank , just for a back up. :)
Yes i feed them mulbery for the ca, and now nettle, also hikaria algae wafers had high ca.
Try shrimp daddys some product for biofilm.
Now waiting some food to try.
With other shrimps there is not problem like this.
From a 30lt tank, I remove 500-600 orange shrimps, and still there was a lot of female with eggs and sandle.
When i move them to another tank
