Look for the uniform bright red to reddish-pink body color, especially in adults. The absence of a distinct black spot on the side is a key differentiator.
Fin Count
Count the dorsal fin spines (10) and soft rays (13-14), and anal fin spines (3) and soft rays (8). Pectoral fin rays (17-18) are also useful.
Body Shape
Observe the deep, compressed body and the relatively large eyes and pointed snout.
Teeth
Note the presence of strong, conical teeth, particularly the two prominent canines in the upper jaw.
