looks like an elusive "sunburst" pattern condition...kind of a mix of xanthic and dark pigment. some fish develop a mix of black and gold as they develop, although most of them lose the pattern.
if you are a seller i would hang on to the fish for a few months to see how it develops...it may be worth a good amount (if it holds the xanthic characters) or it may be worth only normal price (if it loses the pattern). great pics though!--
