Yeah, I've been down the Cichlid route, though I had Mbuna, which are the smaller Cichlids. An all male peacock tank would be cool. I've also seen some cool Texas Cichlids.
My inlaws would tirelessly mock if I got a bass. "Can I fish him" "When are we gonna catch him and cook him up", that sort of thing. They're big fishermen type and go fishing in Canada every year and catch walleye.
What's a Brim? I'll have to research it.
Keep the suggestions coming! I've got time to do research and get this tank moved and ready for a stocking!
