Color brown to red dorsally, paler ventrally, the scale edges darker; scales on body with or without a white or pale blue spot; a darker brown or brownish red stripe, broadly bordered in white, from front of snout through center of eye, becoming indistinct below origin of second dorsal fin; a dark brown spot within stripe behind eye; a second dark stripe across cheek parallel to the first, bordered below by a white band that ends at pectoral-fin base; a white or pale pink spot anteriorly on upper half of caudal peduncle covering about three horizontal rows of scales, followed by a black or dusky spot with darker scale edges a little larger in size (spot may extend slightly below lateral line); fins light red to reddish gray, the second dorsal and anal fins often with small pale spots (Ref. 54393). |
