Lavender. Lighting plays a huge role with this fish and of course the food. Mine really loved the red macro algae from ipsf - gracilaria parvispora. Would go nuts over the stuff as does my scopas. Anyway beautiful tang (biased obviously I am) but sadly mine needed to be given away as it wouldn't let me add any more fish to the tank. It was fine with those it was introduced with but anything after forget it. Mean as can be.
