Environment / Climate / Range
Marine; reef-associated; depth range 1 - 5 m (Ref. 90102). Tropical; 30°N - 30°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.5 cm TL male/unsexed; (Ref. 48636)
(total): 10 - 11;
soft rays: 14. Head and body speckled and mottled; 5-6 indistinct, dark blotches or bands on body usually with dark-edged ocelli above (Ref. 4404). First three rays of dorsal fin are elevated.
Indo-Pacific: Red Sea and East Africa to the Phoenix, Samoan and Tongan islands, north to Ryukyu Islands, south to Australia and New Caledonia.
Adults are found solitary or in small groups (Ref. 90102) in shallow protected lagoons and reef flats with algal and seagrass clumps. Juveniles often in floating Sargassum weeds and maybe dispersed over great distances (Ref. 48636). They swim with the tail oriented vertically. Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Empty mollusk shells are used for nesting. Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Captured at the surface using a hand net (Ref. 26165).

Phylogenetic diversity index (Ref. 82805
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this BS (Ref. 93245
Trophic Level (Ref. 69278
): 2.0 ±0.0 se; Based on diet studies.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (17 of 100) .
