The Diadem Dottyback, more commonly known as the Purple Stripe Dottyback, is a popular aquarium fish. Much like other Dottybacks, this one will aggressively defend caves it finds from other fish, so it should be put in a tank with large, aggressive fish.[1] Its diet consists of meaty foods and shrimp.
