Diagnostic Description

provided by Fishbase
Juveniles and adults resemble their counterparts of B. axillaris, but juveniles have yellow rather than white spots and adults have well-defined black band between the light and dark portions of the body and lack ocelli on the dorsal and anal fins. Color of juveniles changes completely to adult pattern when about 5-6 cm long. The change takes only a few weeks and intermediates are rarely seen (Ref. 48636).

Trophic Strategy

provided by Fishbase
Occurs inshore (Ref. 75154). Ranging into subtropical zones as juveniles expatriate caused by warm currents during pelagic stage (Ref. 48636). Adults inhabit coral-rich outer reef slopes at depths of 5 to over 20 m, particularly near caves. Juveniles in caves; adults swim openly about, but usually close to the substrate, and often engage in cleaning larger fishes (Ref. 48636).

Bodianus mesothorax

provided by wikipedia EN

Bodianus mesothorax, the split-level hogfish, blackbelt hogfish, black-belt hogfish, coral hogfish, eclipse hogfish, eclipse pigfish, mesothorax hogfish or yellow-spotted hogfish,[3] is a species of wrasse native to the western Pacific Ocean and the eastern Indian Ocean.

Description

Bodianus mesothoraxwhich has a distinct blackish diagonal band between the purplish head end of the body and the whitish to yellowish posterior part. The juveniles are dark purple with two lines of bright yellow spots. They are similar to the juveniles of the axilspot hogfish (Bodianus axillaris) although these have white rather than yellow spots.[3] This species can reach a length of 25 cm (9.8 in). The body pattern and colouration of juveniles changes to the adult pattern when they attain a length of 5–6 centimetres (2.0–2.4 in). They take only a few weeks to change completely and intermediate fish are very rarely recorded.[2] The adults are distinguished from the adults of the axilspot hogfish by the dark diagonal band and the lack of spots on the dorsal fin and the anal fin.[3]

Distribution

Bodianus mesothorax is found in the eastern Indian Ocean as far west as the Nicobar Islands in the Andaman Sea and in the western Pacific Ocean from Japan I the north and Australia in the south as far east as Fiji.[2]

Habitat and biology

Bodianus mesothorax can be found on reefs at depths of 5 to 40 m (16 to 131 ft), though rarely below 20 m (66 ft). Juveniles inhabit caves in the reef. Adults of this species clean other fish by eating parasites on the body of other reef fish.[2]

In the aquarium

This species can be found in the aquarium trade.[2] It is commonly imported for the fish trade from the Philippines and Indonesia.[4]
