Common name: Paraferdina
Paraferdina is a genus of sea stars belonging to the family Goniasteridae. These sea stars are known for their strikingly symmetrical, pentaradial body structure and often vibrant coloration, making them a fascinating addition to marine aquariums. While not as commonly kept as some other sea star species, they are highly appreciated by enthusiasts for their unique appearance and the role they play in the ecosystem as scavengers.
Species within the Paraferdina genus are typically found in tropical and subtropical waters, often inhabiting coral reefs or rocky substrates. They are benthic organisms, meaning they live on the ocean floor, and they feed on detritus, algae, and small invertebrates. This diet makes them beneficial in aquariums as they help to clean up uneaten food and organic debris, contributing to the overall health of the tank.
Caring for Paraferdina species in a home aquarium requires stable water parameters, as they are sensitive to fluctuations in salinity, temperature, and water quality. They thrive in well-established tanks with plenty of live rock and a mature biofilter. It is crucial to ensure that they have a sufficient food source, as starvation is a common issue for sea stars in captivity. Supplemental feeding with small pieces of shrimp, fish, or algae wafers may be necessary.
One of the challenges of keeping Paraferdina species is their sensitivity to changes in their environment, including acclimation to a new tank. A slow and careful acclimation process is essential to reduce stress and increase their chances of survival. Additionally, they should not be housed with aggressive tank mates that may nip at their delicate arms.
Overall, Paraferdina sea stars are a captivating choice for advanced aquarists who can meet their specific care requirements. Their unique beauty and ecological role make them a rewarding addition to a carefully maintained marine aquarium.
