if my pike is this aggressive i shouldnt have to worry about the leporinus bullying him do i?It will fight for dominance of the whole tank. Other cichlids allow certain space, and never cross an imaginary line. I had a jag that was top boss, but it rarely crossed the halfway mark of the 8 foot tank, even though the other fish weren't that aggressive. The pike on the other hand, swam across the full length of the tank, beating any fish that wouldn't back down. As long as the other fish back down, it won't receive major injuries from the pike.
