Mine was scraping a bird's nest. He had to go in the sump.
Probably just picking stuff off it.

Ha .No .that what I thought at first .put him back in and caught him doing it again .He had scrapped one side completely off .it just healed this past week .Took 2 weeks for it to heal. He ate it.Probably just picking stuff off it.
I have 2 very large ones. Never caught them picking at corals. The fish are always swating at them. They are scary looking with the big claws grabbing at the fish. I feed them a piece of nori every day so they don’t get hungry and eat corals or fish.
Yh i had the same problem but they never harmed anything in my tankOnly issue I've had with emerald crabs is them picking zoas off of their rock. They don't eat them, but the act of picking them off and then sending them floating around the tank is super infuriating.
