I love Copperbands, I know they are a pain, but if I order from Dr. Reef, I am thinking it's probably eating since it has been in that place for so long. I already have a Heniochus waiting in my QT. I am tempted to a CB once I empty out my qt. Am I pushing it? They both seem to be on the more peaceful side, but you never know with fish. Do you think this can be done in a 125? My other larger fish are Yellow Tang and Powder Blue, and I am not anticipating much trouble from them. My Heni is small, only about 1.5 in.
