Morphology | Morphometrics
soft rays: 7. Most of lateral portion of head and body red while whitish ventrally; relatively large red spots scattered on head and body. Predorsal scales, 8. Head without scales except predorsal to posterior margin of interorbital; characterized further by lacking elongate dorsal spines; all pectoral rays unbranched; branched fifth pelvic ray; longitudinal scale series 24-25; depth of body 4.2-4.3 in SL (Ref. 90102).
Inhabits rubble slopes at the base of vertical cliffs. Typically hovers vertically or obliquely, several centimeters above the bottom (Ref. 31115).

Estimates based on models
Preferred temperature (Ref. 115969
): 27.7 - 28.5, mean 28.2 °C (based on 12 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00454 - 0.02011), b=3.05 (2.88 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
