Luidia is a genus of starfish typically found in shallow waters and sandy substrates. They are known for their distinctive long, slender arms which can regenerate if damaged. Luidia species are often voracious predators, feeding on a variety of invertebrates. In the aquarium, they require ample space and a well-established sand bed to thrive. They can be sensitive to changes in water quality, so stable conditions are essential.
