Biology:  Inhabits sheltered coastal and offshore reefs, usually in turbid areas of bays and lagoons, in 3-40 m (Ref 90102). A nocturnal fish hiding in caves or beneath ledges by day, feeding on plankton such as crab larvae at night. Found in loose aggregations in caves, sometimes with other soldierfish (Ref. 9710).
IUCN Red List Status: Least Concern (LC); Date assessed: 04 March 2015 Ref. (124695)

Country info:  Zama and Fujita (1977) reidentified M. melanosticta of Kurata et al. (1971) as M. hexagona (Lacepède). However, we observed only M. melanosticta in the Ogasawara Islands, and we suspect that Kurata et al. were correct in their identification (Ref. 26066). Also Ref. 33390.
