簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 14 - 15; 背的軟條 (總數): 10-12; 臀棘 3; 臀鰭軟條: 6 - 8. Diagnosis: 15-19 gill rakers on first gill arch; no large spots on flanks; 4-6 bands or 2 rows of dark blotches and short horizontal lines usually visible when stressed; body depth 25.9-39.6%, mean 35.1% standard length; lachrymal depth 24.6-26.8% head length, mean 25.6% HL); base body coloration light brown to ochre; caudal fin rounded to slightly truncate in females, truncate or with some elongate rays in upper lobe (occasionally also in lower lobe) in males; males one third larger than females (Ref. 81260).
Omnivorous, preferring smaller particles including small fish, albeit rarely (Ref. 52307). Polygamous, ovophilic, female mouthbrooding species (Ref. 52307, 81260) that does not form pair bonds (Ref. 52307). Maximum TL was recorded at 16.5 cm (Ref. 5616).

50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
