I am really wanting to get one, im just worried that my fish may pick at it and kill it. I have an emerald crab, but hes about 1.5 in and huge claws, so he can hold his own, but the pom pom crabs seem much smaller and not as agressive. Its mainly the file fish and the puffer that pick at things. I have a royal dottyback that love to pick at small hermit crabs, but i think the crab would be fine with her, shes only about 2-3 inches long
