So my crayfish molted and her claw is very much stuck I have read lots of different opinions on wear to help them get it off or leave them but this is really stuck i tried to slightly tug it to see and it isnt budging so what should I do?

I am not too educated on molting and I'm new to the fish/shrimp world. The reason I'm answering is because two of my Amano shrimp molted and parts of their old shell didn't come off right. I was freaking out and even posted here but didn't get much help. I was just asked about my water parameters. I continued looking online and most things I read just said to leave it alone. I'll say it took like 3-4 weeks for them to completely molt it off. Now they're on and about and living life good again. 

I am hoping your Crayfish is doing better. 

I'm sure eventually it will come off. 🙂
