I have a branching green. Bought it without knowing how aggressive it was. It's beautiful, hardy, & I love it, but if any corals get knocked against it they're done for. Mean son of a gun! Watched it battle a Galaxia for a couple of days before I put even more space between them - only coral I've seen get a few punches in on that horn coral! I'm running out of space for those that "don't play well with others..." but they're so cool!
