Common name: Red Comb Starfish
General Information
The Red Comb Starfish, scientifically known as Astropecten aranciacus, is a fascinating species of sea star found primarily in the Mediterranean Sea and the eastern Atlantic Ocean. Known for its distinctive orange to reddish coloration and comb-like spines along its arms, this species adds a unique touch to marine aquariums. It is not commonly kept in home aquariums due to its specific care requirements and natural habitat preferences.
While not a staple in the pet trade, the Red Comb Starfish is of interest to marine biologists and hobbyists who specialize in echinoderms. It plays a role in the ecosystem as a predator of bivalves and other small invertebrates, thus contributing to the ecological balance of its natural habitat.

Care
Caring for the Red Comb Starfish requires attention to its natural environment. It thrives in sandy substrates where it can burrow and hunt for food. Maintaining stable water conditions and a substrate that mimics its natural habitat is crucial for its well-being. This species is sensitive to changes in water quality, making it more suitable for experienced aquarists.
Diet and Feeding
The Red Comb Starfish is a carnivore, primarily feeding on bivalves and small invertebrates. In captivity, it can be fed a diet of chopped seafood, such as shrimp and clams, to mimic its natural diet. Feeding should occur every few days, ensuring that the starfish has time to digest its food properly.
Behavior and Compatibility
This species is generally peaceful and can coexist with other non-aggressive marine species. However, due to its predatory nature, it may pose a threat to small invertebrates in the tank. It is best housed in a species-specific tank or with other larger marine organisms that it cannot prey upon.
Health and Common Issues
The Red Comb Starfish is susceptible to changes in water quality and requires a stable environment to thrive. Regular monitoring of water parameters and maintaining a clean tank are essential to prevent stress and disease. Signs of poor health include loss of color, lethargy, and disintegration of limbs.
Habitat
Naturally found in the sandy and muddy substrates of the Mediterranean Sea and the eastern Atlantic Ocean, the Red Comb Starfish prefers environments where it can easily burrow and hunt for prey. It is typically found at depths ranging from shallow waters to about 200 meters.
