this is a couple that I use. I would try to narrow your search and then ask again here about the fishes you are considering for your particular setup. For example an Antennata Lionfish. I think the website recommended 55 gallon minimum. Thing is they get as big as a football. Kind of hard to maneuver a football in a 55 gallon, haha.
Best to ask here because some of the guys here know their stuff.
