Yeah, but...your tank has sort of de-sensitized you to the opposite extreme. What with all the bopping, popping, smacking, whacking, head-butting, lip-locking, tail-biting, eye-gouging, gravel-digging, plant-uprooting, chasing, fleeing, patrolling, enforcing and who knows what else...dang, my blood pressure is starting to spike just thinking about it.
Your cichlids have done to you what video games have supposedly done to a generation of youngsters; they have insidiously altered your interpretation of normalcy, to the point where you are happy with a tank full of fish who spend all their time beating the crap out of each other!
