Taille / Poids / Âge
Maturité: Lm ? range ? - ? cm
Max length : 4.5 cm SL mâle / non sexé; (Ref. 7050)
Épines dorsales (Total) : 7; Rayons mous dorsaux (Total) : 6 - 8; Épines anales: 1; Rayons mous anaux: 6 - 7. Distinguished by the following characteristics: slender with compressed head and body; greatly enlarged jaws in adult males with lips distinctively broadened anteriorly and narrowed below eye; body with scale margins outlined forming reticulate pattern; dark band along mid-side of body; head with 4-6 curved oblique dark bands crossing cheek and small dark mark behind upper rear part of eye; variably sized black blotch on posterior part of first dorsal fin; second dorsal rays I,6-8; anal rays I,6-7; pectoral rays 15-18; longitudinal scales 22-25; TRB 7-8 1/2; predorsal scales 6-9 (Ref. 84480).
Body shape (shape guide): fusiform / normal.
Adults inhabit sea and rivers (Ref. 419). Found in estuaries and lower (tidal) reaches of freshwater streams (Ref. 2847). Usually recorded from swift flowing streams, often described as cascades or cascade zone, above or below waterfalls, with solid rock, boulder and gravel substrate. A few sites consisted of mud and sand substrates and one was from a mangrove only 50 m from the shoreline. Gut content of one specimen from Palau contained insect remains and a few nematodes (Ref. 84480).
