I've had a blue throat male triggerfish for years now. When I got him, he was small, about 2.5". He lost his male coloring for about a year, likely due to harassment by a "peaceful" green chromis. He's been back to his normal bright colors for a couple years now.
Great personality - the only fish that will come check out what I'm doing when I'm arm deep in the tank. I've seen our cleaner shrimp cleaning him, and he's never shown an interest in eating anything but fish food and nori. He doesn't do his own aquascaping either. He does have a cave he has claimed for his own, and when he's in there, he pokes his head out through a top hatch which is pretty cool to see.
A couple things to note - screen your top, even if you have a canopy. These fish are jumpers and can injure themselves. Try to get a small one, I've read they adapt to tank life better than a large one.
