Damsels and fish in general can pick on them and usually do!Otto is doing great. Ill upload some pics/videos when I get home tonight. He spends his days tucked wayyyy into his rock. The evenings he sits on top and watches me at my desk. He's eating frozen (clams, shrimp and salmon so far) but still prefers a good emerald crab.
I did put a couple damsels in the tank. He half ass chases them around sometimes, but puts very little effort into it.
