Okay...so in a previous post I mentioned that I had two down, under the "I'm worried" thread. I mentioned I have a lonely crab. Well I go to change water and food and check on him. I go and pick him up and not until I'm holding him do I notice a pile of exoskeleton on the sand. He went and surface molted on me. Now I'm STRESSED OUT that I may have totally upset him because I handled him. I don't understand why he surface molted when he has tank mates who I assume found the sand okay and buried down. UGH!!!!!
