Tropical Indo-Pacific


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.


Max Size: 4 cm

Sea Temperature Range: 16.9-31.5°C

Depth: N/A

Habitat Generalization Index: N/A

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity

IUCN Status: Not Evaluated

Occurrence: Rare (0.5% of sites)

Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed

Abundance: Solitary (1 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
