Default Why are my shrimps all male?

Hi guys, i realised that almost all the shrimps in my tank are male except for one female Any idea what is happening? I dont specially cull away the female shrimps, so why did this happen?

Those are yellow shrimps and i have been keeping them for about a year. I bought them from c328 long time ago and also supplemented with some more from green chapter. I will get more female, but i would also like to know the cause of the problem. Is it due to inbreeding perhaps?

If they are self bred then I think refer to post #2.

It's hard to tell if it's due to in breeding since we won't know where they are originally from whom.

Why not intro another batch from some other places?

ok, i guess most yellow shrimps come from the same source anyway.

Pick individually if you can. That way you can be more certain of females.
