I can say that my lmb is very animated and always front and center. He hasn't touched any of the nori, or food for the other fish. When I got him, he was a little thin, but now seems to be putting on weight. He eats mainly off the back wall, I have OCD..and clean the three walls. But, if I don't, I see lips on the front glass where he has been. He is extremely animated, when the camera comes out, so does he. I worried about him not eating anything else, but he still poos green poo, so I guess he is getting enough to eat. :joy: Never in my life did I think I would be excited to see green poo!!!
But, he is doing great in my reef and causing no harm.
