Back in '97 when I set my tank (85g) up for the first time, the dogface was one of my first fish (following the damsel acclimation mistake). It grew quite fast, and it was my most loved fish. I had all kinds of fish in that tank with him....damsels, tangs, trigger, even a banded cat shark (the lionfish didn't work out too well though). Mind you, at the time I really didn't concern myself with the now conventional stocking methods. He never bothered any of the other fish and they never bothered him. He grew to have a great personality and would even let me 'pet' him on the nose during feeding time (probably trying to eat my finger, but whatever).
I used to drop live crawfish in the tank. He would hunt them down and eat them up. Loved it.
The bioload is heavy, and as previously stated, considerable logs were left behind. Real messy eater.
I would love to have one again, but i'm fairly certain that my peppermint shrimp wouldn't take too kindly to that. Maybe someday.
Good Luck!!!
