That's a nice Emperor! I got mine a little over a year ago at about 3/4" and he looks identical to the third picture. He is in a reef tank with mostly SPS, a couple LPS, and a RBTA. I can only hope he turns out as nice as yours is! What have you been feeding him? Are Spectrum pellets included in his diet? Selcon? Anyway, nice fish and keep us posted. :smokin:
