I know I've seen this post somewhere before but I just couldn't find where, I have a crab in the middle of my tank right now on it's back flailing around. It looks like it's changing colors so I think it's molting but I haven't seen this behavior anywhere else. My tank is still cycling, so any help would be great. I also think I have a Sally Lightfoot that has wedged it self in the rocks any tips of luring it out to get a certain ID on the crab?
