Aquarium Advice Newbie
I have 2 grown fiddler crabs that I have had for about 2 weeks. They were fine until now. I checked the tank today and they were upside down laying on their backs. I thought they were dead but I could see them moving a little bit. When I flipped them back over, one of them started walking around a little bit then flipped over again. I dont know what to do!! Does anyone have any ideas as to whats going on??
