Écologie
marin récifal; profondeur 0 - 5 m (Ref. 86942). Tropical; 12°N - 20°S

Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 10.0 cm TL mâle / non sexé; (Ref. 48635); common length : 4.0 cm TL mâle / non sexé; (Ref. 2871)
Épines dorsales (Total): 6 - 8; Rayons mous dorsaux (Total): 8-12; Épines anales 1; Rayons mous anaux: 12 - 17. Ascending process of premaxilla long and slender; ramus of dentary highly elevated posteriorly; midlateral band wide, broadest between anus and anal fin (Ref. 9760). First dorsal fin above middle of body; second dorsal fin originates behind the beginning of the anal fin; mid-lateral scales 40-43; transverse scales 5; predorsal scales 16-19 (Ref. 2334). Midlateral band width 2.3-3.3 in body depth (Ref. 37816).
Inhabits lagoons and along shorelines of outlying islands (Ref. 3302). During daylight, schooling fish may be periodically seen to jump out of the water to avoid predators. They are also easily attracted to light. The fish are gravid at about 4-4.5 cm SL by July in the northern hemisphere. Because of their large numbers, they are probably important as forage food for larger fishes (Ref. 9760).
