Distribution

Tropical Indo-Pacific

Description

Uniform red-orange spots all over face and body, very similar to T. macrophthalmum, but has slightly larger, often merged spots on lower head. Also lacks discrete circular red spots on the lighter fleshy part of the pectoral fin base.

Almost identical to T. readerae whose body spots look more like vertical rectangles and tend to form rows.
