Why We Like It:

The Coco Worm is a striking filter-feeding invertebrate with a vibrant spiral crown that retracts instantly when disturbed. Peaceful and reef safe, it adds movement and colour to established systems. Best kept in mature tanks with stable parameters and regular plankton feeding. A delicate but rewarding addition for reef keepers focused on biodiversity and visual detail.
