The African schilbeidae (Schilbeidae) come throughout Africa south of the Sahara , with the exception of the Cape , but including the entire Nile ago.
features
They are six centimeters to 1.80 meters long fish that get their name from their light, often almost translucent, whitish to silvery body color. Your body is slender, elongated and compressed on the sides. The head is flat with three to four pairs of barbels on the mouth. The anal fin is very long, has 24 to 90 fin rays and has not grown together with the forked caudal fin . The dorsal fin is short, has a hard ray and is absent from the genus Parailia . The pelvic fins are also missing in some species.
Way of life
African glass catfish are diurnal schooling fish which , like the majority of catfish, do not live on the bottom of the water, but mostly swim lively in open water. Some species usually remain still, only flapping their caudal fin slightly between aquatic plants. African glass catfish feed on smaller fish, crustaceans and insects . They lay eggs .
