Thanks for the help. it's the best picture that I have... I'll try to blow it up. But from what I remember, you could see most everything, the little pinchers, a few legs, and in the back it looks like tissue. I originally thought my pistol shrimp tore it out of it's shell to eat it.
This has happened like 4 times before. I really can't remember if I bought 10 or 5 hermit crabs with my CUC. Before this happened, I remembered only seeing about 4 crabs, so I was really confused about what was happening.
