May not go well with the community stocking plan, but lionfish look awesome from the top view.
Me and my sons have always admired these in when we come across them in a LFS, but they are supposed to be pretty aggressive right? I generally try to avoid fish that need an entire tank dedicated to themselves.
I've been lucky though - I've got a big ol' zebra tilapia (buttikoferi) named buddha that is living peacefully in my cichlid community tank and they have a pretty mean reputation. I've failed more often than I've been successful in getting mean fish to get along, I've had to trade away quite a few flower horns in my attempts to get a peaceful one.
Maybe one day I'll consider a lionfish
