The size of both males and females at first sexual maturity is about 160 mm fork-length. Each female of T. jentinki jentinki lays between 110 and 420 eggs depending on the size. It represents an average of about 1,100 eggs/kg weight. The female keeps the eggs in its mouth: this oral incubation reaches an average of 15 days at the end of which the released fry measures from 12 to 20 mm fork length.
