A pike, wow. Double wow. That is one hell of a big fish. Even in 125 gallon tank, a pike, wow. Alls I know is that they're kinda like gars in that they grow very big, live very long, and are very very predatious and nasty (so watch your fingers). I've had juvinales in the pet shop before, and boy did they suck down rosies. Great for population control if your cichlids breed like rabbits<G>. Good luck with it.
