Common name: Egyptian Sea Star

Scientific name: Gomophia egyptiaca Gray, 1840

General Information

The Egyptian Sea Star, scientifically known as Gomophia egyptiaca, is a strikingly beautiful species of sea star found in the Indo-Pacific region and the Red Sea, particularly around coral reefs and rocky substrates. Its vibrant coloration, often featuring a mix of red, orange, and purple hues with intricate patterns, makes it a popular choice for marine enthusiasts seeking a visually captivating addition to their aquariums.

This species is not only admired for its aesthetic appeal but also for its role in maintaining the ecological balance of reef systems. As a scavenger, it helps clean up detritus and uneaten food, contributing to the overall health of the aquarium environment. However, its care requirements and dietary preferences make it more suitable for intermediate to advanced hobbyists.

Care

The Egyptian Sea Star requires a well-established marine aquarium with stable water parameters. It thrives in tanks with plenty of live rock and sandy substrate, which provide both food sources and hiding spots. This species is sensitive to sudden changes in water quality, so consistent monitoring and maintenance are essential.

A minimum tank size of 120 liters (30 gallons) is recommended to accommodate its active foraging behavior. The tank should have moderate water flow and ample surface area for the sea star to explore. Avoid housing it with aggressive tank mates that may nip at its arms or stress it.

Diet and Feeding

In the wild, Gomophia egyptiaca is an omnivorous scavenger, feeding on detritus, algae, and small invertebrates. In captivity, its diet should include a mix of natural detritus, algae wafers, and meaty foods like chopped shrimp or clam. Supplementing its diet with marine-specific pellets or frozen foods can help ensure balanced nutrition.

Feed the Egyptian Sea Star every few days, placing food near its location to encourage feeding. Observing its feeding behavior can help determine the appropriate frequency and portion size. Avoid overfeeding, as uneaten food can degrade water quality.

Behavior and Compatibility

The Egyptian Sea Star is generally peaceful and spends most of its time foraging along the substrate and live rock. It is compatible with a variety of reef-safe fish and invertebrates, though caution should be exercised with delicate corals or small sessile invertebrates, as it may inadvertently damage them while foraging.

This species is best kept singly or in pairs, as overcrowding can lead to competition for food and stress. It is not known to exhibit aggressive behavior but may become stressed in the presence of overly boisterous tank mates.

Health and Common Issues

With proper care, the Egyptian Sea Star can live for several years in captivity. Maintaining stable water parameters and providing a varied diet are key to its health and longevity. It is sensitive to poor water quality and sudden changes in salinity or temperature, which can lead to stress and disease.

When selecting an individual, look for a sea star with intact arms and vibrant coloration. Avoid specimens with signs of damage, discoloration, or lethargy. Quarantining new additions can help prevent the introduction of diseases or parasites to the main tank.

Common health issues include bacterial infections and tissue necrosis, often caused by poor water quality or physical injury. Prompt treatment and improved tank conditions can help mitigate these problems.

Habitat

Gomophia egyptiaca is native to the Indo-Pacific region, including the Red Sea, where it inhabits coral reefs and rocky substrates. It is typically found at depths ranging from shallow tidal zones to around 30 meters (100 feet). Its natural habitat is characterized by warm, clear waters with abundant live rock and coral formations.

Replicating these conditions in captivity involves maintaining stable water parameters. Providing a mix of live rock and sandy substrate helps mimic its natural environment and supports its foraging behavior.
