Fishfur
Aquarium Advice Addict
They should be ok, but there is a chance the fish are bothering them, even if not eating them. Might be why they are climbing out.. just a guess.. I have not had dwarf shrimp do this to me, only fan shrimp, who often decide to go find another pond. Carpet surfers, poor things. Making a screen top for their tank.
CO2 is not, so far as I know, any kind of issue with shrimp, unless you add too much in which case fish die too, suffocated. But that's not the issue you have.
I wonder if perhaps the fert levels are a bit high for them ? Do you dose much trace ? Some trace mixes may have a bit too much copper in them, maybe.. just trying to think of things that might have an effect on them. Do you mix ferts into water first, then dose or just dump it in ? Dry or premixed wet ? Perhaps grasping at straws here, but there has to be a reason, for so many shrimp to do this. One or two, yeah, it happens, but not this many.
