Very cool Paul. I have a Burrfish as well. I caught mine Mother's Day 2007, the size of a pea drifting in the waves at the beach. She has grown many times over, and as of today is at least 10". The fastest growth rate of any fish I've ever kept. She's leveled off in the last half year. You are right about them being puppy dog, they have so much personality.
Here's a vid of her I just took, munching down a jumbo shrimp (her fav). She is quite the mouth to feed at this size.
