Folded shell?

[Yevy]

I've recently noticed that one of my shrimps has an abnormality in its shell. Looks as if the left part of the shell is folded up, exposing the tissue underneath. Apart from that, the shrimp is still active, eating well and behaving as per usual. All limbs working normally. Just wanted to ask if anyone else had this issue and if this was something to worry about, or likely just results of a physical injury?

 

They're currently together with some guppies, a bristle nose, a corydora and a crab, but haven't seen any of its tank mates bullying it. 

 

Sorry the pics aren't the best, still practicing with the camera.

I have the same problem with some of my shrimps too!!! I just thought it was an issue during molting. Many times they die off, but if they survive until the next molt it will go back to normal.

Might be time to double check your water parameters, just in case!
