CPO Dwarf Crayfish Issue

[NOLANANO]

I have a CPO that is laying on its back looking dead but when i go to grab it, it kicks its feet and is very much alive. I put her right side up but she managed to flip onto her back within a few minutes and remains motionless unless I try to touch her.

I assume she is dying but was wondering if anyone had any idea what is happening so that I might save my other CPO from the same fate? Or maybe I can even save her.

I have Neocardina in the tank and they are molting just fine so I'd be shocked if it were a molting issue.

Parameters:

temp:78-80 F

PH: 7.5

Amonnia and Nitrite: 0

Nitrate: 15 ppm

GH/KH: both fairly high but not sure of a number.

It can be molting. If it is, then touching it is the literal last thing you want to do. Let it be, either it’s molting or it’s dead, either way, touching isn’t the cure. Give it time and see what happens.

I only touched her because she looked dead. I will leave her for the time being and see what happens.

Agreed with @mynameisnobody. I’ve seen my CPO’s in some rather precarious situations, and then they’re cruising around. I bet they’re molting. 
 

CPO’s in my experience are kinda like cockroaches. They just keep going and going and going.

Maybe she's having trouble with buoyancy? Have you tried feeding her differently or adding some plants to help her swim more easily?

No animal will eat during a molt, most will even continue to fast until they harden up. The threat of death or serious injury when you’re a soft invert is very high.
