Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 4421)
soft rays: 22 - 25. Body brown with up to 12 narrow dark brown crossbars; caudal fin dark brown; soft dorsal, anal and pectoral fins pale; lips dark brown (Ref. 4421). Males with numerous long spines in front of caudal peduncle; females with a toothbrush-like mass of setae (Ref. 1602).
Indo-Pacific: Red Sea south to Maputo, Mozambique (Ref. 4421) and east to the Society and Tuamoto islands, north to the Gotô Islands, Japan (Ref. 559), south to the southern Great Barrier Reef.
Inhabits clear coastal to outer reefs, usually in rich coral areas with rubble patches or gutters (Ref. 48637). Feeds on coral polyps (Ref. 89972). Solitary or in pairs (Ref. 90102). Less approachable than most filefishes (Ref. 9710). Usually seeks coverage in large corals when approached (Ref. 48637).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00983 - 0.04439), b=2.92 (2.74 - 3.10), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.9 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (30 of 100) .
