Emerald crabs are unpredictable. Yes they are good at pick the rocks and cleaning detris. When they get bigger they can change there taste. I had one destroy my millie. It would pick at it every night until half was gone. It would even stalk my baby clownfish . But, it was picky, left other sps alone. No more crabs for me. especially hairy ones.
