Mushroom Coral

About

Mushroom coral (Danafungia horrida) is a solitary, free-living stony coral found across the Western Central Pacific, turning up on reef flats and slopes anywhere from just below the surface down to around 40 meters. Unlike most hard corals that cement themselves permanently to the substrate, this one sits unattached on sandy or rubble-strewn areas, which gives it a surprisingly mobile existence. The disc-shaped skeleton is covered in sharp, irregular ridges radiating outward from a central mouth, giving the surface a rough, almost spiky texture that sets it apart from the smoother mushroom corals people sometimes confuse it with. In the aquarium, it does well under moderate lighting and prefers gentle water movement rather than a strong, direct current. Too much flow can stress the tissue. For a large-polyp stony coral, it is reasonably forgiving, which makes it an accessible entry point for hobbyists who want to keep hard corals without immediately jumping into high-maintenance species. It will generally feed on meaty foods target-fed directly to the disc, and keeping it on a sand bed rather than propping it on rockwork tends to suit it better.
