The Harlequin Tusk, Lienardella fasciata, is a wonderfully unique aquarium fish. They exhibit the most vibrant orange colors found on any fish and beautiful white vertical striping. Neon blue and green stripes can often be found across their faces. Harlequin Tusks possess large teeth that they use to crush small crustacean prey.
Like other unique large fish, there are some specifications that should be heeded while keeping a Harlequin Tusk. They should usually be kept in a fish-only aquarium with only one Tusk per tank.
