Hello. So, for starters, my crayfish molted for the first time the other day! It was pretty funny because a few hours later, he came out of hiding to grab his old shell. Then, he drug it around with him from hiding spot to hiding spot until he had the whole thing eaten. I tried to get pictures of this but couldn't because I left the lights off during this time to not stress him out. I do have a question though. Before his molt, I noticed this white spot on his side. It's still there after his molt. It looks like this. What is that? Could it be from an old shell fracture injury, and it's going to take a few molts to get rid of it? Should I do anything?
