I recently cycled my tank and I entered the ugly stage so I got some clean up crew. My LFS recommended some emerald crabs along with a handful of other things. After I took them home and put them in the tank, I did some research because I thought that I’ve heard emerald crabs aren’t reef safe. I currently have 2 anemones and I am going to add more corals soon. Will the emerald crabs eat my corals? Should I take them out?
