Silver-blue body with a yellow tail fin and rear body, yellow extends along back for about 2/3 of the body, to almost in line with front of pectoral fin, black spot at base of pectoral fin. Differs C. cuning (Yellowtail Fusilier) by having a more slender body profile and more yellow on back, and from two similar non-fusiliers, Paracaesio xanthura (False Fusilier) and Labracoglossa nitida (Blue Knifefish), by lacking narrow blue line below dorsal fin, and possessing spot at base of pectoral fin.

• Max Size: 40 cm
• Sea Temperature Range: 21.7-31.4°C
• Depth: 5-50m
• Habitat: Coral Reef
• Habitat Generalisation Index: 9.5
  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).

• IUCN Threat Status: Not Evaluated
• Occurrence: Infrequent (9% 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: Large aggregations (102 per transect)
  Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
