Always found with shrimp. Distingiushed from a number of similar species in the genus by the arrangement of brown markings along the side of the head and body. Previously often confused with C. maculosus, which is apparently only known from the Red Sea, but has a highly similar arrangement of brown spots. Where they both occur in the Red Sea, C. maculosus can be distinguished by a brown v-shaped marking on the snout in front of the eyes and small vertical yellow marks on the side of the belly and pectoral fins. 


Max Size: 10 cm

Sea Temperature Range: 23.7-30.3°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: Infrequent (3.5% 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: Few (2 per transect)

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