help with feeding CBB

[surgeonfish]

fishoholic:
For the first 2-3 weeks, my CBB also looked non stressed and appeared to be actively looking for food mostly on the bottom. He would occasionally pick at the live rock and sand but don't think he was actually eating anything. He refused anything except blood worms. He did get pretty thin.


Delphinus:
Besides the CBB, what else is in your tank? Do you have any aggressive eaters such as tangs that would out compete the CBB. My fish is now eating blood worms. However, he still takes his sweet time inspecting each worm before eating it. I think he will starve in my main tank with several hungry tangs and damsels.
