This seems to be yet another hitchhiking crab making his appearance. I know I have a ruby mithrax in there that just shed, so I am hoping this is just him looking slightly different. This "new" crab is red like the ruby and about the same size as the decorator and porcelain I found, maybe 3/4" long from leg to leg. His claws seem to be slightly hairy, and so does his body, but just barely. His other legs are hairy like my emerald and ruby. Could this be a gorilla crab? There is no way for me to catch him , he's already been in the system for 5 months and no coral or nem has been harmed by any inhabitants.
