I have a mated pair of gold stripe maroon clowns in my 72g reef tank. Other inhabitants: Chromis, basslet, Coral Beauty, mated pair of Banggai cardinals, anthias. They usually spend the day chasing away other fish who get too close to their anemone. They don't harm any of the other fish. They do attack my hand when I do maintenance which isn't bad while they are still young. When they get bigger, I imagine it won't feel too good.
