Care
Caring for Iconaster longimanus requires a well-established aquarium with stable water conditions. They are sensitive to changes in water quality and require a tank with plenty of live rock and a sandy substrate to forage on. It's important to provide a varied diet that includes meaty foods such as shrimp, squid, and clams. Overfeeding should be avoided to maintain optimal water quality.
Reproduction
Reproduction in Iconaster longimanus is not well documented in home aquariums. In the wild, they reproduce by releasing gametes into the water column, where fertilization occurs externally. Hobbyists should be aware that breeding these sea stars in captivity is challenging and rarely observed.
Symbiosis
While not known for any specific symbiotic relationships, Iconaster longimanus can coexist with a variety of reef inhabitants if provided with the right conditions. They should be kept with caution around small, sessile invertebrates, as they may prey on them.
Habitat
Iconaster longimanus is found in the Indo-Pacific region, typically in coral reef environments. They prefer areas with strong water movement and are often observed at depths ranging from the reef crest down to the reef slope.
