features
Charax species grow to be 3.5 to 12.8 inches long. Your body is high back, the sidelines are complete. The head profile is almost horizontal at first, to rise steeply behind the eye so that a concave shape results. In the intermaxillary bone (premaxillary) the teeth sit in two, often irregular rows. The dental (lower jaw) has a row of teeth. The anal fin is long and scaly, the caudal peduncle is long, the caudal fin is deeply forked. An adipose fin is present.
Charax species live mainly in the reed belts of their living waters and stand in a characteristic sloping position with their heads down. They are not very fond of swimming.
Charax is closely related to Roeboides . The species in this genus are getting larger.
