Awesome fish, great to look at and good in a reef. The problem? They WILL jump out of the tank and die. So unless you have a lid, or some way to keep them from landing on the carpet, you would do well to pass on them.
Mine lasted a cool week and I found it dried up like jerky behind the tank a couple days later.
I got one about two months ago for my birthday and at that time I was warned about their jumping habits. Despite the fact I was too lazy to put a lid on so the second day I had him he tried to jump out but fortunately he hit the bottom of the horizontal pane of my tank and fell back in. The fortunate thing is he hasn't done that since. I was told these guys like to stay in one spot, but the one I have moves around all over my 120 and loves to follow people when they walk by. I guess I just lucked out on a good individual one.
