Well I opened the tank to change out all the water. Rawlings was under the salt water basin, hanging out of his shell. I thought I disturbed a molt so I put the bowl back and waited a few days. My curiosity got the best of me so I checked again and He was still in the same location so I pulled him out and confirmed a death. Rawlings is the crab I've had the longest, about a year and a half or so. Rawlings was my buddy. The sweetest crab to handle. Never afraid to be picked up and loved to crawl up my arm. I'll miss ya buddy! Thanks for always putting a smile on my face!
