Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 8; Raios dorsais moles (total) : 9 - 11; Espinhos anais: 3; Raios anais moles: 9 - 11. Diagnosis: Ambassis natalensis has following combination of characters: supraorbital spines 1-4; rostral spine absent; rear margin of preopercle entirely serrate; preopercle ridge smooth except for 1-5 tiny spines at rear corner; interopercle smooth or with 1-4 tiny serrae at angle; two rows of cheek scales; predorsal scales 9-11; lateral line continuous; lower gill rakers 19-22; pectoral-fin rays 14-15; teeth on vomer and palatines in 2-3 rows (Ref. 50956).
Tolerant of freshwater within a temperature range of 19-27°C (Ref. 4180, 52193, 79840). In summer, it feeds mainly in early evening and late morning while in winter, it feeds both day and night on crustaceans as well as insects (aquatic and terrestrial) and fish (Ref. 7248, 52193). Excellent subject for biological research as it easily thrives in captivity (Ref. 12484).
