Add a mesh top. No top =equals= no wrasse. All wrasses jump. Through small holes. When you least expect it. I know! But if you use find mesh screen as a top, it will work and not look too bad or block too much light, so I've heard. I'm still building mine.
My yellow Coris jumped last month. I have a full top but it was open because I was changing bulbs. I turned my back literally 2 seconds to grab a fresh bulb, and that was all it took. He hasn't been seen since! There wasn't even a scary noise to cause him to jump in the first place. He just saw his chance and went for it.
