Common name: Indian Sea Star

General Information

The Indian Sea Star, scientifically known as Fromia indica, is a captivating addition to marine aquariums, renowned for its vibrant red coloration and star-shaped body. This species is often sought after by hobbyists for its striking appearance and relatively peaceful nature. Native to the Indo-Pacific region, Fromia indica is typically found in shallow reef environments where it plays a role in the ecosystem as a scavenger.

While it is not as famous as some other marine species, the Indian Sea Star contributes to the biodiversity of reef aquariums and can be an intriguing specimen for those interested in the diverse forms of marine life. Its unique shape and color make it a visually appealing choice for aquarists, and it can serve as an educational tool for learning about echinoderms and their ecological roles.

Care

Caring for the Indian Sea Star requires attention to detail, as it thrives in well-established marine tanks with stable water parameters. It is sensitive to changes in water chemistry, particularly salinity and pH, making it more suitable for experienced aquarists. A mature tank with plenty of live rock is ideal, as it provides the microalgae and biofilm that the sea star grazes on.

The tank should be equipped with proper filtration and regular water changes to maintain optimal conditions. While Fromia indica is generally peaceful, care should be taken to ensure it is not housed with aggressive species that might nip at its delicate arms.

Diet and Feeding

In its natural habitat, the Indian Sea Star feeds on biofilm, detritus, and microalgae found on live rock surfaces. In captivity, it relies heavily on the established microfauna within the tank, making it essential to have a well-matured aquarium. Supplementing its diet with occasional offerings of marine pellets or specially formulated starfish food can help ensure its nutritional needs are met.

Behavior and Compatibility

The Indian Sea Star is known for its peaceful temperament, making it an excellent addition to community reef tanks. It spends much of its time slowly moving across the substrate and live rock in search of food. Unlike some other starfish species, Fromia indica is not known to be aggressive towards tank mates and can coexist with a variety of reef-safe species.

While it is generally reef-safe, care should be taken to monitor its interactions with delicate corals, as it may occasionally rest on them.

Health and Common Issues

Indian Sea Stars can live for several years in captivity if provided with proper care. Maintaining stable water conditions and a mature tank environment are crucial for their health. When selecting a specimen, look for bright coloration and intact arms, as these are indicators of a healthy individual.

Common issues include susceptibility to changes in water parameters and potential starvation in tanks that lack sufficient biofilm. Regular monitoring and careful acclimation can help prevent these problems.

Habitat

Naturally found in the warm, shallow waters of the Indo-Pacific region, the Indian Sea Star thrives in coral reef environments. It prefers rocky substrates where it can graze on biofilm and detritus. Replicating these conditions in captivity involves providing plenty of live rock and maintaining stable water parameters.
