When I did a deep clean months later, I found him still alive, still missing legs. However, he had become very sluggish (more-so than normal indo sluggishness) and I hand-fed him honey and peanut butter for a few days to give him a boost (which took forever because he wouldn't come out of his shell for about 20 minutes when I first would pick him up).
He dug down, molted, and re-grew both his missing legs. I expected him to be more outgoing and active, but he started hiding again, and after months of not seeing him, I was convinced again that he must be dead. I have literally seen him out on his own <10 times in the last year. But for the last week or so, he has been hanging out with the other indo by the pools!

He seems to be very healthy. Still shy, and more skittish than indos normally are (he acts like a purple pincher), but I am very happy to actually be seeing him instead of wondering if he is dead. He has even been sleeping with all the other crabs up on the second level! I wonder what brought on this sudden personality change? Maybe it was the longest de-stressing period ever. hahaha
So don't give up on your shy crabs!! Their personalities can change.
