The Purple Stripe Dottyback (Pictichromis diadema), also known as the Diadema Dottyback, can be found among the reefs of Eastern Asia. They hide among rock and coral, where they feed on small crustaceans and other invertebrates. They have a vibrant yellow body with a pink streak that covers their face and dorsal section. They reach a maximum size of 3 inches and should be housed in an aquarium with at least 30 gallons. They may be aggressive towards others of the same species or territorial towards tankmates near their burrows. They should be fed carnivorous preparations, such as mysis or krill, and require plenty of live rock to hide in. Lids are recommended, as dottybacks have been known to jump.
