I added a large (around 5 inch) Copperband Bfly that I picked up form my LFS about 5 days ago. The first few days he was deathly afraid of my and would dissappear in LR if there was any chance I was there. He picked at bloodworms and mysis and looked like he would only eat about 3 pieces of each before he decided he didn't want anymore. He would go crazy though for the giant bristleworms that would come out to eat the food. I picked up some blackworms from an lfs today and he is eating it like crazy. However many i put in the tank he finishes them all. Are blackworms nutritious enough to sustain a CBB? also even though he eats pretty nicely he scratches on the rocks every now and then. I know this can't be good but i dont have a qt. He also doesn't seem to have any marks on him that indicate an infection. Any suggestions on what i should do
