I still think that the giant snakehead with give the aimara a serious run for its money. It's a feeding time only aggression though.
If you are taking to that level, why not just go Great White Shark? Win!I don't know if anyone have tiger shark, they are the most aggressive shark!
great white are not as aggressive as tiger! GW are just big and curious, and they try to eat every thing rather than attack everything!If you are taking to that level, why not just go Great White Shark? Win!
I have those tilapia before, they got beat up by the same size oscar and flowerhorn!In my experience, pikes can be seriously aggressive too... I had a bellycrawler that would pick fights with my firemouth who was twice his size, and win. And that firemouth wasn't peaceful either...
But again, for their size, I think people are forgetting about the Tilapia Buttikoferi.
Those two I think are right up there... Especially if you get into the larger pikes (12"+)
