Steatocranus bleheri is a species of cichlid that is previously only known from the Kafubu . The Kafubu is a river in the catchment area of the Luapula , the headwaters of the Luvua , which in turn is a right tributary of the upper Congo in the southeast of the Democratic Republic of the Congo .
features
Steatocranus bleheri reaches a standard length of about 7 cm and a total length of 9 cm. Compared to other Steatocranus species, Steatocranus bleheri is relatively high back. The muzzle is short, the forehead profile is steep. There is no clear head hump like other Steatocranus species. The fish are colored gray. On the sides of the body you can see two dark longitudinal stripes that begin behind the gill covers or behind the eyes and merge on the tail stalk. A sexual dimorphism is only slightly developed. Males become a little larger and the soft-rayed sections of their dorsal and anal fins are more clearly drawn out. The lower pharyngealia are occupied with an average of 151 teeth and on the lower section of the first gill arch there are five broad gill rakes . Overall, Steatocranus bleheri resembles Steatocranus mpozoensis from the Mpozo , which flows east of Matadi into the lower Congo.
- Fin formula : dorsal XX-XXI / 7-8, anal III / 6–7.
Way of life
Steatocranus bleheri lives in small groups of up to 20 individuals on the stony bottom of the water. Nothing more is known about reproductive biology. Like other Steatocranus species, Steatocranus bleheri will be a cave-breeder that forms a father-mother family .
Systematics
Steatocranus bleheri was described in 1993 by Manfred K. Meyer , an employee of the Staatliches Museum für Tierkunde in Dresden , and named after the ichthyologist Heiko Bleher , who caught the holotype .
