Pseudanthias caudalis has been assessed as Least Concern. This species typically occurs on offshore deepwater reefs where it is protected from collection for the aquarium trade and inshore pollution sources. This species is likely to be locally abundant.

Population [top]

Population: There is no population information available for Pseudanthias caudalis, however the life history characteristics of the Anthiinae subfamily (short-lived, high natural mortality rate, high growth rate and high recruitment rate) (Russ and Alcala 1998) suggests that this species may be locally abundant.
Current Population Trend: Unknown
Additional data:
Population severely fragmented: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Pseudanthias caudalis is a demersal species that has a depth range of 50-100 m and can be found over coral and rocky substrates. This species forms schools above the reef (P.C. Heemstra pers. comm. 2009). This species mixes with other anthiids while feeding on zooplankton above the reef (Kuiter and Debelius 2007).
Systems: Marine

Threats [top]

Major Threat(s): Due to the deep water nature of this species, it is not commonly seen within the aquarium trade (P.C. Heemstra pers. comm. 2009). This species largely occurs on offshore reefs where it is unlikely to be impacted by inshore pollution (P.C. Heemstra pers. comm. 2009). The use of piscicides is prohibited within Japanese waters (P.C. Heemstra pers. comm. 2009) so this is unlikely to pose a threat.
