I had one of these before, the entertainment value was great! Definitely make sure you have a nice, large zoa colony. Mine grew fast & always tried to get new zoas instead of reusing the ones from the molt & had to be encouraged. His fav pasttime was getting to the highest rock, taking 5 minutes to gather his nerve, then bonzai off the edge & float to the bottom, immediately running right back up. He'd do that for an hour or two at a time. He was orange & always wore the orange polyps. I later got a burgundy female after a tank crash, and she did nothing but wear sponge on her head, no fun stuff.
