Common name: Brown Mesh Sea Star

General Information

The Brown Mesh Sea Star, scientifically known as Nardoa galatheae, is a fascinating species of sea star that captivates both marine enthusiasts and reefkeepers. Known for its intricate mesh-like pattern on its dorsal surface, this species is a beautiful addition to any marine aquarium. Its unique appearance, combined with its relatively peaceful nature, makes it a popular choice among hobbyists looking to diversify their invertebrate collection.

This species is not just a visual delight but also plays a role in the ecosystem as a scavenger, helping to maintain the cleanliness of the tank by consuming detritus and leftover food. However, it is crucial to ensure that these sea stars are sourced responsibly to prevent overharvesting from their natural habitats.

Care

Caring for the Brown Mesh Sea Star requires attention to water quality and stability. They thrive in aquariums that closely mimic their natural reef environment, with plenty of live rock for grazing. These sea stars are sensitive to changes in salinity and temperature, so maintaining stable conditions is vital for their health.

A tank with a capacity of at least 100 liters is recommended to provide ample space for movement and exploration. The inclusion of live rock not only offers grazing surfaces but also provides hiding spots and contributes to the overall biological filtration of the aquarium.

Diet and Feeding

In the wild, the Brown Mesh Sea Star primarily feeds on detritus and small invertebrates. In captivity, they should be offered a varied diet that includes meaty foods like chopped shrimp, clam, and specially formulated sea star pellets. Regular feeding ensures they receive adequate nutrition, as they might not get enough sustenance from scavenging alone in a closed aquarium system.

Behavior and Compatibility

The Brown Mesh Sea Star is generally peaceful and can coexist with a variety of reef-safe fish and invertebrates. They are non-aggressive and do not pose a threat to corals or other tank inhabitants, making them an excellent choice for community reef aquariums. However, care should be taken to avoid housing them with predatory species that might see them as a meal.

Health and Common Issues

These sea stars are relatively hardy but can be prone to stress if exposed to poor water quality or drastic changes in environmental conditions. Symptoms of stress include loss of limbs or a decline in activity. Regular monitoring of water parameters and gradual acclimation to new tank conditions can help prevent these issues.

When selecting a Brown Mesh Sea Star, look for individuals with intact limbs and vibrant coloration. Avoid sea stars that appear lethargic or have visible damage, as these could be signs of underlying health problems.

Habitat

Nardoa galatheae is naturally found in the Indo-Pacific region, inhabiting coral reefs and rocky substrates. They prefer shallow waters with plenty of hiding spots and a stable environment that mimics their natural habitat. In captivity, replicating these conditions helps ensure their well-being and longevity.
