The Double Tile Starfish, Iconaster longimanus, also known as the Double Starfish, or Icon Starfish, has a large scaly pentagon-shape body with scaly limbs. It ranges from bright orange to tan and has distinctive tile shaped patterns. The central pentagon resembles a second starfish giving the Double Tile Starfish its name. As a scavenger, the Double Tile Starfish prefers tanks with sandy substrates and plentiful rock work allowing it places to hide. It should only be kept as a singular individual unless in a very large tank that can support two Double Tile Starfish. The Double Tile Starfish is quite intolerant to changes in water quality so tanks should be kept stable and established. Overall, the Double Tile Starfish is incredibly unique and makes an excellent star to keep in the home aquarium. It is active and will no doubt be a fan favorite.
