This is from nowhere Zimbabwe...and it's been featured on this site before and elsewhere on the www. (search for goliath tiger). The very same pics in fact
This is a Hydrocynus goliath of average size. A species endemic of the Congo drainage system.....also in L Tanganyika. Occurs no where near the Zambezi system, and is also absent from Lakes Mweru and Bangweulu in the "Zambian" Congo system, but is recorded from Lake Upemba on the Upper Lualaba in Katanga. the largest specimens are known from the Lower Congo along the 'Cuvette Centrale'.
I am reliably informed that this specimen was caught by locals on the Kwango river
beautiful fish of note
