Mushroom Coral

About

Mushroom coral (Fungia puishani) is a solitary, free-living coral found across the western Indian Ocean, ranging from the Gulf of Aden down to the Seychelles. In the wild it settles on reef slopes and lagoon floors anywhere from shallow water down to about 30 meters, typically resting unattached on sandy or rubble substrate rather than cementing itself to rock. A trait that sets it apart from most reef-building corals. The body is a single circular to oval disc, growing up to around 125 millimeters across, with a noticeably domed profile. The upper surface is covered in densely packed, straight septa lined with small blunt teeth, giving the disc a fine, almost comb-like texture when you look closely. A single well-defined central mouth sits at the top, surrounded by numerous smaller peripheral mouths spaced between septa of varying lengths. There are no tentacle lobes along the edge. Coloration in the wild tends toward pale brown, though aquarium specimens can sometimes show more variation depending on lighting. In a reef tank this is a reasonably approachable coral for newer keepers. It appreciates moderate lighting and gentle, low flow, and its free-living nature means it can be repositioned easily if conditions aren't quite right.
