Emerald green crab... it's alive!!!

This morning I woke up sad to see a flipped over Emerald crab in the sand when I turned the lights off before heading to work. I did a 15% water change the day before and was convinced I killed it. I then read that most people mistake molts for dead crabs. Tonight I spotted the smaller crab and then the one that must have molted hiding right in the middle of a large green sinularia leather coral looking bigger and more beautiful than ever!!! Woohoo!!! I'm not a murderer :)
