I keep them together with Yamato shrimp and Red Cherry shrimp.
All the shrimps are fine but the bees are dying one after another again.

My tank parameter:
kH=5
NO2 = 0
NH3/NH4 = 0
pH is about 7- 7.5
I have put in some Indian almond leave, hopefully it will lower the pH further.
Unfortunately, the tannin make the water so dark that I cannot see the shrimp...

Can someone advice me how to keep them alive ?
Does anyone have any success breeding them ?
