The broad- band bottom tetra ( Nannocharax parvus ) is a freshwater fish from the African tetra family of the Distichodontidae and occurs in West Africa in the catchment areas of the Niger rivers to Ogowe and Chiloango . Possibly the species is synonymous with Nannocharax ansorgii .
features
The fish are 6 cm long. Your body is elongated and only slightly flattened on the sides. Their color is olive brown with a clear silvery sheen. A wide, dark brown to deep black longitudinal band runs from the tip of the mouth over the eye to the tail. The males are slimmer than the females. Seen from above, the two body ties appear straight in the males, while in the females they look like they are curved.
