The Barred Hamlet (Hypoplectrus puella)  is a species of sea bass found in the Atlantic Ocean. They have a black or brown body with yellow stripes and vertical streaks. They are safe around corals, though they should be monitored around small invertebrates, as they will likely eat them. They have a peaceful disposition and can be kept in a reef or fish only aquarium with other fish of similar size and temperament. Reaching a maximum size of 5 inches, they should be kept in a tank of at least 55 gallons. Their diet should consist of carnivorous preparations, such as mysis or krill.
