So i had my Yellow Eye Kole Tang for 2 weeks now and he still isnt eating any prepared food or Nori. I tried rubberbanding it to some rock and clipping it on the side of my tank. He acts like its not even there all he does it peck at the rock all day. Any suggestions?? Should i be worried?? He looks fine and healthy swimmimg all around and haging out with the other fish??
