I'm going to have to get fid of these guys in a month or two for a new tank, but their colors aren't what I have hoped. I feed them frozen every now and then, but stick to Formula two flakes and Formula one pellets and nori for the most part. The Yellow tang is a bit pale in the face at times and the Coral beauty is begining to loose color on his face. What could I do to improve their colors a bit? I heard broccoli is good, and zuchini, but what else can I feed them out of the fridge? Thanks
