I just lost my Crocea of about 4 years. I am really upset. About a week and a half ago it stopped opening up completely. The mantle would come out about half way. it still responded to light change. All parameters are fine. i have another large deresa which is doing fine. I took the crocea out early on to check for parasites but did not find any. When i came home today it was dead. When I lifted him up off the rock I saw a huge bristle worm or maybe a fire worm come out from him. Could this have been the culprit or was the worm just getting a free lunch after it was already dead?
