Common name: Sohari Starfish

General Information

The Sohari Starfish, scientifically known as Paraferdina sohariae, is a fascinating species of sea star native to the waters around Sri Lanka and the Andaman Islands. This starfish is a relatively rare find in the aquarium trade, making it a prized addition for dedicated marine enthusiasts. Its unique appearance and ecological role in its natural habitat make it a species worth appreciating.

This starfish is characterized by its striking coloration, typically featuring a mix of red and brown patterns that help it blend into its surroundings. Its five arms are robust and slightly tapering, giving it a classic starfish shape. While it may not boast the vibrant colors of some other marine species, its understated beauty and intriguing behavior make it a captivating addition to any tank.

In the wild, Paraferdina sohariae plays an important role in maintaining the health of coral reef ecosystems. By scavenging detritus and organic matter, it helps keep the reef clean and balanced. This ecological contribution, combined with its rarity, underscores the importance of responsible collection and care for this species.

Care

Keeping Sohari Starfish in captivity requires a stable and mature marine aquarium. They thrive in tanks with plenty of live rock, which provides both a source of food and hiding spots. A well-established reef tank with stable water parameters is ideal for this species. As with most starfish, they are sensitive to changes in water quality, so maintaining pristine conditions is essential.

This species is best suited for aquarists with some experience in marine tank care, as they require specific attention to their diet and environment. Avoid exposing them to sudden changes in salinity or temperature, as these can cause stress and health issues.

Diet and Feeding

Paraferdina sohariae is a detritivore, feeding primarily on organic matter, algae, and biofilm found on live rock and substrate. In captivity, they can be supplemented with small pieces of meaty foods such as shrimp or fish, as well as algae wafers or specialized starfish diets. Ensure that food reaches the starfish, as they are slow feeders and may struggle to compete with faster tank mates.

Feeding should be done sparingly, as overfeeding can lead to water quality issues. Monitor their behavior and adjust feeding frequency based on their activity and the availability of natural food sources in the tank.

Behavior and Compatibility

Sohari Starfish is a peaceful and slow-moving species, making it an excellent addition to community reef tanks. They are non-aggressive and pose no threat to other tank inhabitants, including fish, corals, and invertebrates. However, they may occasionally graze on biofilm or detritus near corals, so ensure that your corals are healthy and not stressed.

This species is best kept in tanks with other peaceful inhabitants. Avoid housing them with predatory fish or invertebrates that may see them as a potential meal. Their slow movement and delicate structure make them vulnerable to aggressive tank mates.

Health and Common Issues

Sohari Starfish can live for several years in captivity if provided with proper care. However, they are sensitive to poor water quality and sudden changes in tank conditions. Regular water testing and maintenance are crucial to their health.

When selecting a Sohari Starfish, look for individuals with intact arms and a firm, healthy appearance. Avoid specimens with signs of damage, discoloration, or lethargy, as these may indicate underlying health issues.

Common health problems include tissue necrosis and stress-related issues caused by poor water quality or improper acclimation. To prevent these, ensure a slow and careful acclimation process when introducing them to your tank.

Habitat

In the wild, Paraferdina sohariae is found in the shallow waters around Sri Lanka and the Andaman Islands. These regions are characterized by warm, tropical waters with abundant coral reefs and rocky substrates. The starfish thrives in environments with plenty of hiding spots and a steady supply of detritus and organic matter to feed on.

To replicate their natural habitat, provide a tank with live rock, sandy substrate, and stable water conditions. Moderate water flow and consistent lighting will help mimic the gentle currents and natural light conditions of their native environment.
