Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 5.5 cm TL male/unsexed; (Ref. 9710)
Dorsal spines (total): 12 - 13; Dorsal soft rays (total): 16 - 18; Anal spines: 2; Anal soft rays: 19 - 20; Vertebrae: 34 - 37. Dorsal fin XII or XIII (rarely XII),16-18 (rarely 18), deeply notched between spinous and segmented ray sides. Anal fin II,19 or 20. Pectoral fin 13-15 (typically 14). Segmented caudal-fin rays 13. Vertebrae 10 or 11 (rarely 10) + 23-26 (typically 24 or 25) = 34-37 (rarely 34). Dentary
incisor teeth which includes anterior canine teeth very similar in appearance with incisors 46-57; posterior dentary canines 0 or 1 (rarely 0) on each side. Lateral line without pairs
of pores, terminating posteriorly at a point between verticals from dorsal-fin spines 8 and 10. With cirrus on posterior rim of anterior nostril; absent on anterior rim.
Adults occur in coral reefs. Secretive (Ref. 9710). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models
Preferred temperature (Ref.
123201): 24.5 - 27.4, mean 26.4 °C (based on 32 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00356 - 0.01695), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
