Tony, you are right as usual. The Potters is from Hawai and the Rusty is from the Indo-Pacific.

The distructive behaviour is probably their tendancy to nip at corals.

I would think if they are well fed they may not nip.

According to Scott Michael's Marine Fish the Potters is ranked as a green/yellow, whereas the Rusty is ranked as a yellow for aquarium suitability.

Yellow = these species are moderately hardy, with most individuals acclimating to the home aquarium if special care is provided.

Green/Yellow = these species are generally durable and hardy, with most individuals acclimating to the home aquarium.
