Common name: Nardoa Tuberculata

General information

Nardoa tuberculata, commonly known as the Tuberculate Sea Star or Horned Sea Star, is a species of sea star found in the Indo-Pacific region. It is recognized for its distinctive horn-like tubercles covering its body and arms, which give it a unique texture and appearance. This sea star can exhibit a variety of colors, ranging from brown to green, often with mottled patterns that help it blend into the reef environment.

Care

The Tuberculate Sea Star is a fascinating addition to a reef aquarium but requires a mature system with ample live rock and a stable environment. It feeds primarily on detritus, small invertebrates, and algae, making it a beneficial scavenger. However, it is sensitive to sudden changes in water parameters and should be acclimated slowly to prevent stress. It's important to ensure that the aquarium does not have predatory fish that may harm the sea star.

Reproduction

Reproduction in Nardoa tuberculata typically involves broadcast spawning, where males and females release sperm and eggs into the water column. In the aquarium, this behavior is less common, but under the right conditions, it can occur. The larvae are planktonic before settling and metamorphosing into juvenile sea stars.

Habitat

Nardoa tuberculata is found in a range of reef habitats, from shallow lagoons to deeper slopes, usually within a depth range of 3 to 20 meters. It prefers areas with plenty of crevices and live rock where it can forage for food and hide from predators. Its natural distribution includes the Red Sea, the Indian Ocean, and the western Pacific Ocean.
