Crenicichla. Pikes do awesome with plants. From the tiny dwarf species to the big Lugubris brutes. I've done heavily planted tanks with 12+ inch pikes with awesome results. Try a nice saxitilis species. You will be pleasantly surprised.
How big do those grow? Tank is a 75 and it has gouramis (for now) so they can't beat them up.
Also, idk where to find pike cichlids.
