A nice open brain, red rim, would be a good beginner add. IME you never know what you will have luck with and what you won't. Everyone seems to have that one variety coral that doesn't take. Me, it seems to be certain monti caps, with the exception of purple varieties. I can keep other hard species, like a purple monster frag that seems to be growing quick, so it's not like a water quality issue.
Just try different things, if something doesn't take, don't sweat it. Don't overspend at the beginning until you know things are set and stable.
