A book I have says that in ' most cases ' they ARE safe with most corals and inverts except worms like feather dusters.
Hardy, yes
gets 8 inches
varied diet, mostly frozen foods
Peacefull
keep singularly
Ditto the Dog. If you have Feather Dusters they will be gone. Or any worms. Other than that, great fish. I know lots of people with them. I am getting one myself for my tank.
