Tiny black creatures in shrimp shedding

[Reinjs32 0]

I'm brand new to shrimp keeping and breeding so pardon any ignorance.  I have some Blue Neocaradina shrimp, probably about a month or so old.  I checked the shedding/shell (not sure what's the correct term) of one just after it had moulted. 

 

I noticed some very small little black dots, moving, crawling around in the shedding.  It can't be seen with the naked eye, I could only see it when I used a jeweller's loupe.  They seem a bit more concentrated at the tail end.  Not sure if this is normal or a parasite to be worried about.

 

Any advice or insight would be helpful, thanks

Iv'e never kept neo's personally. Its called a molt btw and its alright, we all start off somewhere. This doesn't sound very normal though. I think it could be a parasite, someone else probably has more info since iv'e never kept neo's. hope this was somewhat helpful!
