The Spanish Dancer Nudibranch, Hexabranchus sanguineus, is a versatile nudibranch that is red and white in color with frilly edges. Some say then nudibranchs undulating movement resembles a Flamenco dancer giving it its name. It is reef safe, peaceful, and feeds primarily on algae, flatworms, and boiled kelp. They should not be kept with aggressive or predatory species and are best kept in tanks with plenty of live rock.
