The orange bush fish ( Microctenopoma ansorgii ) is a species from the genus Microctenopoma , which belongs to the family of climbing fish (Anabantidae). It lives in herbaceous sections of smaller flowing waters in the area of the Congo Basin , is predominantly nocturnal and feeds on small invertebrates.
features
The orange bushfish has an elongated, laterally flattened body and reaches a length of eight centimeters. It is brownish to yellowish brown with a bluish or purple tinge on the flanks. The ventral side is often yellowish. Six or seven dark transverse stripes, which are narrower than the spaces between them, extend over the sides of the body and continue on the dorsal and anal fin. The spaces between the fins are reddish, their tips and the front fin rays of the pelvic fins are white. The caudal fin is orange or dark brown. Males are usually more strongly colored.
In the single, continuous dorsal fin, one can clearly distinguish a hard-rayed and a soft-rayed part. It is supported by 14 to 18 fin spines and 9 to 12 soft rays. The anal fin usually has nine to ten fin spines and 10 to 12 soft rays.
Occurrence
The orange bushfish is native to the Congo Basin, in the north to Cameroon and the Central African Republic and in the south from northern Angola to the south of the Democratic Republic of the Congo. Orange bushfish are found in smaller rivers and streams with low currents and dense vegetation.
Reproduction
The orange bush fish builds a foam nest for reproduction . The nest consisting of air pearls is usually anchored to floating plants. The spawning process takes place under the nest and, when the water level is low, near the bottom of the water. The eggs rise up into the nest due to their fat content. The larvae hatch after about 24 hours, the larvae swim free after three days. During this time, the foam nest is guarded by the male.
