White Crayfish Molting Issues

A little off topic for Planted Tank Forum but hard to find reliable info elsewhere.

I purchased a white crayfish an inch big around 6 months ago. The first 2 months he molted 3 times and tripled in size. He molted again a few months ago and mostly recently the other night. (3 inches in length now)

Recently I had a Malawi crab in there with him as both were very passive. The crab unfortunately died of shell rot but not before loosing most his limbs and massive shell decay which was evident at purchase; but I was unaware of what it was at the time . Around the same time he was added I noticed my white crayfish began having black spots on his claws whick looked very similar (I dont think it's contagious and seemed too soon to be so I think coincidence. I read they can sometimes shed the disease off so in an effort to rid it I made sure he was able to eat a lot of protein rich foods like bloodworm as well as algae wafers.

To my delight he molted the other day. Unfortunately he molted differently than before where he normally would molt in one piece; This time was several. I could tell his shell was getting hard and he had molted all but his last right pincher claw so in an effort to help him I removed him and tried helping.

He seemed almost willing for my help and barely struggled and I could tell his shell was almost fully hardened and this was last hope as it was half way off. Unfortunately after what seemed forever with tweezers his new claw fell off still attached to the old one .

His coloring looks good (no visible dark spots) but now he's down a claw.

Does anyone have any recommendations on a diet/ any ways that will help him promote a healthier shell, easier molt next time and a way to speed up the molting process so he can hopefully regrow his claw back quicker?

You didn't mention any Kh/Gh readings, but I will tell you that crays in general do not like soft water. They actually tend to do better in slightly hard water or better.

Feeding an excess of protein to inverts will cause molting issues. From what I read from your post, I am just assuming you fed him a diet of protein more than what you would do normally in hopes for him to molt off the possible disease he was getting.

Just go back to a balanced diet you were feeding him where there was no molting issues and things should be fine.
