Eponymy: Bloch did not identify whom he was naming this fish after, but a probable candidate is Count Ewald Friedrich von Herzberg (1725–1795), a distinguished Prussian statesman and savant and one of Bloch’s sponsors. (Ref. 128868), visit book page.

Adults occur in turbid estuaries, mangrove-lined lagoons and lower parts of rivers being very tolerant to changes in salinity. Found on shallow soft bottoms (Ref. 5217). Feed on a large variety of bottom-living and pelagic organisms including those found among the roots of mangroves. Reproduction occurs between September and December. A female lays 20-30 eggs, with a diameter of 10-12 mm. Males incubate the eggs in their mouth (Ref. 35381).

Females reach maturity at a younger age than males and grow faster. The male incubates 28-40 eggs in the mouth and 200-400 eggs that are fixed in a glutinous mass on its head. Incubation takes 10-12 days. After 50-60 days fully functional young (6-6.5 cm TL) are released.南美洲: 加勒比海與大西洋注入來自哥倫比亞到巴西的河與河口。
