Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 14 - 16; Μαλακές ραχιαίες ακτίνες (συνολικά) : 9 - 11; Εδρικές άκανθες: 6 - 8; Μαλακές εδρικές ακτίνες: 8 - 10; Σπόνδυλοι: 25. Diagnosed from all other species of Australoheros by having only 25 vertebrae and by a combination of the following characters: three abdominal bars in all stages of life; a conspicuous; rounded caudal-fin base spot; a conspicuous wide longitudinal stripe; head with depression in the region above the eyes; tip of pelvic fin reaching vertical through third to sixth anal-fin spine base; 14-16 dorsal-fin spines; 11-13 pectoral-fin rays; 12 caudal vertebrae; 22 proximal radials on dorsal-fin base, 13 proximal radials on anal-fin base; 11 pleural ribs; caudal peduncle length 9.3-13.4% SL; caudal peduncle depth 16.5-22.7% SL; a wide ectopterygoid; last anal-fin spine length 14.4-20.8% SL; and lower jaw length 19.6-28.4% SL (Ref. 87295).
Found in Lagoa Gambazinho, a small and elongated oligotrophic lake situated within Parque Estadual do Rio Doce (PERD) with maximum depth of 10.3 m without occurrence of thermal stratification. Adults feed on shrimp Macrobrachium jelskii, fish, aquatic and terrestrial insects, plant materials and other invertebrates. Immature individuals take zooplankton, mainly cladocerans as food. Smallest mature female and male measure 5.0 and 7.2 cm TL, respectively (Ref. 87295).
