I have had my tang for about 3 weeks. He is eating well but he will not eat the nori that I place in there for him. It loves to clean the rock and the glass. Should I worry that it is not getting enough greens?
I wouldn't worry too much, but I would try alternate ways of serving it. I would try to rubber band it to a rock. Then, I would try crumbling it, like flake food. If that doesn't work, try different types of seaweed.
