Max length : 15.5 cm TL 雄鱼/尚未辨别雌雄; (Ref. 124149); 15.3 cm TL (female); 最大体重: 17.00 g (Ref. 124149); 最大体重: 17.00 g

Adults spawn apparently during autumn and early winter. Hatching probably occurs in spring and size at hatching at about 12 mm TL. Main food items are polychaetes and benthic crustacean (Ref. 5192). Larval pelagic phase is short (Ref. 41551).
显然地在秋天与初冬的时候产卵。 可能孵化出现于春天中而且于大约 12 mm TL 孵出的大小。 主要部份食物组成是多毛类与底栖的甲壳动物。
