Characterized by semi-translucent body with irregular, internal reddish midlateral stripe; white stripe along spinal column interrupted by reddish bars that extend ventrally; row of small reddish spots along dorsal midline; usually with narrow reddish bars above anal fin; often prolonged and filamentous first four dorsal spines of male and first three of female; unbranched pectoral rays; longitudinal scale series 21-24; ctenoid scales, absent on head , nape and pectoral fin base; depth of body 4.3-5.0 in SL (Ref. 90102).
Adults live for 59 days at the most, with larvae spending three weeks in the open ocean and maturing within two weeks of settling on a reef, leaving the adults (which are 1 to 2 centimeters long) just three weeks to reproduce. This strategy of 'live fast, die young' is perceived to be a response to intense predation. Daily mortality rate, from tag-recapture data, might be as high as 8% (Ref. 54199). Occur at depths less than 4 to between 17 and 21 m on sandy bottoms of lagoon reefs (Ref. 1602, 37816, 48637). Minimum depth from Ref. 58018.

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00270 - 0.01286), b=3.10 (2.92 - 3.28), based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.1 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (tmax=0.16; Fec = 400 (lifetime)).
Vulnerability (Ref.
59153): Low vulnerability (10 of 100) .
