I have one in my reef tank, never nipped at anything that wasn't supposed to be eaten.

Mine gets scared easily, and will run and hide or just sit in a corner looking brown and spotted. No feeding issues at all, he eats both red and green nori like there's no tomorrow, same with spiriluna flake and the regular 4 flake frenzy that I feed the rest of the tank, but he never touches the mysis or bloodworms when I feed those.
Hasn't picked on anyone, and no issues with getting bossed around by my big maroon clown. He even lets the cleaner shrimp clean him from time to time.

(knock on wood) Never been stung.

He does frequently hide in the anthelia that's growing wild in my tank, almost clownfish and anemone like.
