Marine Sea Star • Sandbed Cleaner • Detritus Hunter • Reef Aquarium Invertebrate
📋 The Sand Sifting Sea Star (Astropecten polycanthus) is a fascinating marine echinoderm known for its ability to burrow beneath the substrate and sift through sand in search of food.
It functions as a Natural Sandbed Cleaner, consuming detritus, small invertebrates, and organic debris while helping maintain substrate health.
This species spends most of its time buried beneath the sand, emerging during feeding periods or when exploring the tank.
In mature marine aquariums with deep sandbeds, it thrives as an Efficient Substrate Maintenance Invertebrate.
