Care

Feather stars require specialized care and are recommended for experienced aquarists. They thrive in well-established aquariums with moderate to strong water flow and high water quality. It is crucial to provide a varied diet of planktonic foods to mimic their natural feeding habits. They are sensitive to changes in water parameters, so stability is key.

Reproduction

In the wild, feather stars reproduce by releasing sperm and eggs into the water column, where fertilization occurs. In captivity, breeding Comaster schlegelii is quite challenging and rarely observed. Hobbyists should focus on providing optimal care to maintain the health of these animals.

Symbiosis

While Comaster schlegelii does not have notable symbiotic relationships like some marine organisms, its presence can contribute to the overall biodiversity and balance of a reef aquarium.

Habitat

Comaster schlegelii is typically found in the Indo-Pacific region, from shallow reef flats to deeper slopes. They often perch on coral outcrops or sponges, extending their arms into the current to capture food particles.
