sorry to say but i already tried that and the butterkoffi lost quick, he would of been killed but my wife saved him, the butterkoffi was about 12-13 inches, i posted those pics on ***********, the butterkoffi in my most humble opinion is a nasty fish, but i've had large butterkoffis in with small africans many times, with the butterkoffi being the one being chased...this pike just swallows you...i'm in the hobby over 17 years, and i've had many fish, heck i had a dorado 15 years ago when no one ever even saw them, and i've only seen a hand full of fish with the BALLS, and attitude of a male marmoratta pike. please don't make me laugh, a butterkoffi, thats ridiculous, they are wide bodied, but their mouths are to small, and once their bluff is called they become really skittish, so they at least are very smart. ps. nasty fish are my life, i rank the marmoratta in the top six.
