All invertebrates need calcium supplementing or calcium enriched diets for them to grow and molt properly. A diet rich in protien also will cause them to grow faster than the rate of shell development which results in premature molting. Many can survive with partial molts but with obvious deformities like lost limbs. Learn more about dosing the water column with calcium. It is easy and inexpensive.

Also for a tank with the stock lighting, id recommend not having any floaters as it makes a low light tank that much darker. If you wanted to keep floaters, get a few larger ones like frog bit or dwl where the shrimp can feed off their biofilm. Duckweed doesn't offer this benefit and just serves to multiply and choke light out.

Good luck.

but I am curious what you guys think about the cause - I wasn't really supplementing the tank for hardness or calicum or anything for shrimps/crays - any advice here? only thing I did was a few weeks back I started giving the tank some fluval shrimp granules.

so yeah, today I found him dead, apparently halfway molted and he just didn't have it to complete the molt :'(

craycray was a loved member of the 5gallon community from the start back in july - may he rest in peace in my pet cemetery - and out of respect I might retire the 5gallon from CPO keeping perhaps indefinitely.
